Alarm Output Connection Section 3 - Operation3-1Main BoardThe Main Board is shown in Fig. 3-1. Here are the important components on the board:(1) - Terminal Block for Power & Output connections(2) - Single Turn Potentiometer to adjust Emissivity in tenths (0.x_)(3) - Single Turn Potentiometer to adjust Emissivity in hundreds (0._x)(4) -Slide switch to select between real time (Normal Operation) and alarm set point(5) - Alarm set point adjust, P4(6) - Sensor Head connection(7) - Input Zero adjust, P3(8) - Input Span adjust, P2(9) - Output Zero adjust, P5(10) - Output Span adjust, P6Figure 3-1. Main PC Board3.2Ambient TemperatureThe Sensing head can operate in an ambient temperature of 0 to 70°C (32to 158°F). The Sensing head in the high temperature model (-HT) can operate in an ambient temperature of 0 to 85°C (32 to 185°F) without any cooling required. The Sensing head can operate up to 200°C (392°F) using the water cool jacket accessory OS100-WC (See Fig. 3-6).There is a warm up period of 3 minutes after power up. After the warm up period, temperature measurement can be made.When the ambient temperature around the sensor head changes abruptly,the sensor head goes through thermal shock. It takes a certain amount of time for the sensor head to stabilize to the new ambient temperature. For example, it takes about 30 minutes for the sensor head to stabilize going from 25°C to 50°C (77 to 122°F) ambient temperature.The sensor head dimensions are shown in Fig. 3-2.Figure 3-2. Sensor Housing3-23-33.3Atmospheric QualityEnvironments with smoke, dust, and fumes dirty up the optical lens, and cause erroneous temperature readings. To keep the surface of the optical lens clean, the air purge collar accessory is recommended, OS100-AP , See Fig. 3-7.3.4Measuring TemperatureBefore starting to measure temperature, make sure that the following check list is met:ߜ The power and analog output connections are made (Fig. 2-1).ߜThe sensor head is connected to the main unit.ߜThe slide switch (SW1) on the main board is set to real time (Fig. 3-1).ߜThe target is larger than the optical field of view of the sensor head (Fig. 3-3).ߜThe emissivity adjustment on the main board is set properly (Fig. 3-1).ߜThe output load is within the product specification.On OS102 transmitters, follow these additional steps:ߜ The temperature display is set to °F or °C (Fig. 3-4)ߜ For 4-20mA output models, make sure an output load is added, ie. 250ohms.Figure 3-3. Optical Field Of ViewFigure 3-4. Setting the Temperature Engineering Unit3.5Alarm SettingThe unit provides 0-100% alarm set point adjustment. Here is an exampleof an alarm setting.• An OS101-MA(4/20 mA output), the alarm is to be set at 400°Ftemperature.• Connect the alarm output as shown in Fig. 2-2.• Set the slide switch (SW1) on the main board to the Alarm position.• Measure the analog output, and set the Potentiometer P4 until theoutput reads 10.4 mA which is 40% (400°F) of the temperature range.40 x (20-4)[10.4mA=+ 4]100• Set the slide switch (SW1) back to the Real Time position.• If the temperature reading is below the alarm set point, the alarmoutput stays high, otherwise it goes low.On the OS102, you can set the alarm set point directly based on thetemperature display.3.6Adding Extension CableYou can add extension cable between the Sensor Head and the mainelectronic housing up to 15.2 m (50 feet). After adding the extension cable,the Zero input potentiometer, P3 may be re-adjusted.

Generalized WDVV equations for B_r and C_r pure N=2 Super-Yang-Mills theory

a r X i v :h e p -t h /0102190v 1 27 F eb 2001Generalized WDVV equations for B r and C r pure N=2Super-Yang-Mills theoryL.K.Hoevenaars,R.MartiniAbstractA proof that the prepotential for pure N=2Super-Yang-Mills theory associated with Lie algebrasB r andC r satisﬁes the generalized WDVV (Witten-Dijkgraaf-Verlinde-Verlinde)system was given by Marshakov,Mironov and Morozov.Among other things,they use an associative algebra of holomorphic diﬀter Ito and Yang used a diﬀerent approach to try to accomplish the same result,but they encountered objects of which it is unclear whether they form structure constants of an associative algebra.We show by explicit calculation that these objects are none other than the structure constants of the algebra of holomorphic diﬀerentials.1IntroductionIn 1994,Seiberg and Witten [1]solved the low energy behaviour of pure N=2Super-Yang-Mills theory by giving the solution of the prepotential F .The essential ingredients in their construction are a family of Riemann surfaces Σ,a meromorphic diﬀerential λSW on it and the deﬁnition of the prepotential in terms of period integrals of λSWa i =A iλSW ∂F∂a i ∂a j ∂a k .Moreover,it was shown that the full prepotential for simple Lie algebras of type A,B,C,D [8]andtype E [9]and F [10]satisﬁes this generalized WDVV system 1.The approach used by Ito and Yang in [9]diﬀers from the other two,due to the type of associative algebra that is being used:they use the Landau-Ginzburg chiral ring while the others use an algebra of holomorphic diﬀerentials.For the A,D,E cases this diﬀerence in approach is negligible since the two diﬀerent types of algebras are isomorphic.For the Lie algebras of B,C type this is not the case and this leads to some problems.The present article deals with these problems and shows that the proper algebra to use is the onesuggested in[8].A survey of these matters,as well as the results of the present paper can be found in the internal publication[11].This paper is outlined as follows:in theﬁrst section we will review Ito and Yang’s method for the A,D,E Lie algebras.In the second section their approach to B,C Lie algebras is discussed. Finally in section three we show that Ito and Yang’s construction naturally leads to the algebra of holomorphic diﬀerentials used in[8].2A review of the simply laced caseIn this section,we will describe the proof in[9]that the prepotential of4-dimensional pure N=2 SYM theory with Lie algebra of simply laced(ADE)type satisﬁes the generalized WDVV system. The Seiberg-Witten data[1],[12],[13]consists of:•a family of Riemann surfacesΣof genus g given byz+µz(2.2)and has the property that∂λSW∂a i is symmetric.This implies that F j can be thought of as agradient,which leads to the followingDeﬁnition1The prepotential is a function F(a1,...,a r)such thatF j=∂FDeﬁnition2Let f:C r→C,then the generalized WDVV system[4],[5]for f isf i K−1f j=f j K−1f i∀i,j∈{1,...,r}(2.5) where the f i are matrices with entries∂3f(a1,...,a r)(f i)jk=The rest of the proof deals with a discussion of the conditions1-3.It is well-known[14]that the right hand side of(2.1)equals the Landau-Ginzburg superpotential associated with the cor-∂W responding Lie ing this connection,we can deﬁne the primaryﬁeldsφi(u):=−∂x (2.10)Instead of using the u i as coordinates on the part of the moduli space we’re interested in,we want to use the a i .For the chiral ring this implies that in the new coordinates(−∂W∂a j)=∂u x∂a jC z xy (u )∂a k∂a k )mod(∂W∂x)(2.11)which again is an associative algebra,but with diﬀerent structure constants C k ij (a )=C k ij(u ).This is the algebra we will use in the rest of the proof.For the relation(2.7)weturn to another aspect of Landau-Ginzburg theory:the Picard-Fuchs equations (see e.g [15]and references therein).These form a coupled set of ﬁrst order partial diﬀerential equations which express how the integrals of holomorphic diﬀerentials over homology cycles of a Riemann surface in a family depend on the moduli.Deﬁnition 6Flat coordinates of the Landau-Ginzburg theory are a set of coordinates {t i }on mod-uli space such that∂2W∂x(2.12)where Q ij is given byφi (t )φj (t )=C kij (t )φk (t )+Q ij∂W∂t iΓ∂λsw∂t kΓ∂λsw∂a iΓ∂λsw∂a lΓ∂λsw∂t r(2.15)Taking Γ=B k we getF ijk =C lij (a )K kl(2.16)which is the intended relation (2.7).The only thing that is left to do,is to prove that K kl =∂a mIn conclusion,the most important ingredients in the proof are the chiral ring and the Picard-Fuchs equations.In the following sections we will show that in the case of B r ,C r Lie algebras,the Picard-Fuchs equations can still play an important role,but the chiral ring should be replaced by the algebra of holomorphic diﬀerentials considered by the authors of [8].These algebras are isomorphic to the chiral rings in the ADE cases,but not for Lie algebras B r ,C r .3Ito&Yang’s approach to B r and C rIn this section,we discuss the attempt made in[9]to generalizethe contentsof the previoussection to the Lie algebras B r,C r.We will discuss only B r since the situation for C r is completely analogous.The Riemann surfaces are given byz+µx(3.1)where W BC is the Landau-Ginzburg superpotential associated with the theory of type BC.From the superpotential we again construct the chiral ring inﬂat coordinates whereφi(t):=−∂W BC∂x (3.2)However,the fact that the right-hand side of(3.1)does not equal the superpotential is reﬂected by the Picard-Fuchs equations,which no longer relate the third order derivatives of F with the structure constants C k ij(a).Instead,they readF ijk=˜C l ij(a)K kl(3.3) where K kl=∂a m2r−1˜C knl(t).(3.4)The D l ij are deﬁned byQ ij=xD l ijφl(3.5)and we switched from˜C k ij(a)to˜C k ij(t)in order to compare these with the structure constants C k ij(t). At this point,it is unknown2whether the˜C k ij(t)(and therefore the˜C k ij(a))are structure constants of an associative algebra.This issue will be resolved in the next section.4The identiﬁcation of the structure constantsThe method of proof that is being used in[8]for the B r,C r case also involves an associative algebra. However,theirs is an algebra of holomorphic diﬀerentials which is isomorphic toφi(t)φj(t)=γk ij(t)φk(t)mod(x∂W BC2Except for rank3and4,for which explicit calculations of˜C kij(t)were made in[9]we will rewrite it in such a way that it becomes of the formφi(t)φj(t)=rk=1 C k ij(t)φk(t)+P ij[x∂x W BC−W BC](4.3)As aﬁrst step,we use(3.4):φiφj= Ci·−→φ+D i·−→φx∂x W BC j= C i−D i·r n=12nt n2r−1 C n·−→φ+D i·−→φx∂x W BCj(4.4)The notation −→φstands for the vector with componentsφk and we used a matrix notation for thestructure constants.The proof becomes somewhat technical,so let usﬁrst give a general outline of it.The strategy will be to get rid of the second term of(4.4)by cancelling it with part of the third term,since we want an algebra in which theﬁrst term gives the structure constants.For this cancelling we’ll use equation(3.4)in combination with the following relation which expresses the fact that W BC is a graded functionx ∂W BC∂t n=2rW BC(4.5)Cancelling is possible at the expense of introducing yet another term which then has to be canceled etcetera.This recursive process does come to an end however,and by performing it we automatically calculate modulo x∂x W BC−W BC instead of x∂x W BC.We rewrite(4.4)by splitting up the third term and rewriting one part of it using(4.5):D i·−→φx∂x W BC j= −12r−1 D i·−→φx∂x W BC j= −D i2r−1·−→φx∂x W BC j(4.6) Now we use(4.2)to work out the productφkφn and the result is:φiφj= C i·−→φ−D i2r−1·r n=12nt n D n·−→φx∂x W BC j +2rD i2r−1·rn=12nt n −D n·r m=12mt m2r−1[x∂x W BC−W BC]j(4.8)Note that by cancelling the one term,we automatically calculate modulo x∂x W BC −W BC .The expression between brackets in the ﬁrst line seems to spoil our achievement but it doesn’t:until now we rewrote−D i ·r n =12nt n 2r −1C m ·−→φ+D n ·−→φx∂x W BCj(4.10)This is a recursive process.If it stops at some point,then we get a multiplication structureφi φj =r k =1C k ij φk +P ij (x∂x W BC −W BC )(4.11)for some polynomial P ij and the theorem is proven.To see that the process indeed stops,we referto the lemma below.xby φk ,we have shown that D i is nilpotent sinceit is strictly upper triangular.Sincedeg (φk )=2r −2k(4.13)we ﬁnd that indeed for j ≥k the degree of φk is bigger than the degree ofQ ij5Conclusions and outlookIn this letter we have shown that the unknown quantities ˜C k ijof[9]are none other than the structure constants of the algebra of holomorphic diﬀerentials introduced in [8].Therefore this is the algebra that should be used,and not the Landau-Ginzburg chiral ring.However,the connection with Landau-Ginzburg can still be very useful since the Picard-Fuchs equations may serve as an alternative to the residue formulas considered in [8].References[1]N.Seiberg and E.Witten,Nucl.Phys.B426,19(1994),hep-th/9407087.[2]E.Witten,Two-dimensional gravity and intersection theory on moduli space,in Surveysin diﬀerential geometry(Cambridge,MA,1990),pp.243–310,Lehigh Univ.,Bethlehem,PA, 1991.[3]R.Dijkgraaf,H.Verlinde,and E.Verlinde,Nucl.Phys.B352,59(1991).[4]G.Bonelli and M.Matone,Phys.Rev.Lett.77,4712(1996),hep-th/9605090.[5]A.Marshakov,A.Mironov,and A.Morozov,Phys.Lett.B389,43(1996),hep-th/9607109.[6]R.Martini and P.K.H.Gragert,J.Nonlinear Math.Phys.6,1(1999).[7]A.P.Veselov,Phys.Lett.A261,297(1999),hep-th/9902142.[8]A.Marshakov,A.Mironov,and A.Morozov,Int.J.Mod.Phys.A15,1157(2000),hep-th/9701123.[9]K.Ito and S.-K.Yang,Phys.Lett.B433,56(1998),hep-th/9803126.[10]L.K.Hoevenaars,P.H.M.Kersten,and R.Martini,(2000),hep-th/0012133.[11]L.K.Hoevenaars and R.Martini,(2000),int.publ.1529,www.math.utwente.nl/publications.[12]A.Gorsky,I.Krichever,A.Marshakov,A.Mironov,and A.Morozov,Phys.Lett.B355,466(1995),hep-th/9505035.[13]E.Martinec and N.Warner,Nucl.Phys.B459,97(1996),hep-th/9509161.[14]A.Klemm,W.Lerche,S.Yankielowicz,and S.Theisen,Phys.Lett.B344,169(1995),hep-th/9411048.[15]W.Lerche,D.J.Smit,and N.P.Warner,Nucl.Phys.B372,87(1992),hep-th/9108013.[16]K.Ito and S.-K.Yang,Phys.Lett.B415,45(1997),hep-th/9708017.。

(18 Kgs)V THEORY AND OBSERVATIONS OF GRILL OPERATIONThe Hot Dog Grill is designed for any concession application for re-heating hot dogs,frankfurters and other pre-cooked sausages. They are suitable for English style, un cookedsausages, but will require a higher thermostat setting (contact manufacturer). HotDogs/Frankfurters must be completely de-frosted before cooking.All hotdog grills operate on a “heat and hold” principle. The pre-set grill plate temperature will heat the sausages in a matter of minutes and hold them for several hours with little or nodeterioration in appearance or taste. This unique feature allows the HOT DOG GRILL tomaximize the merchandising potential with the minimum of supervision. If t here are any signs of deterioration, the grill plate temperature should be lowered, see “GRILL PLATETEMPERATURE” instructions.VI CONTROL SWITCHVII INSTALLATION INSTRUCTIONS1.

FAILUSE TO DO SO COULD RESULT IN A HUMAN INJURY OR MAJOR EQUIPMENT DAMAGE. REFER TO THE PROXVIEW SOFTWARE USER GUIDE (P50228) FOR DETAILED PROGRAMMING INSTRUCTIONS.• DO NOT USE THIS PRODUCT FOR HUMAN SAFETY APPLICATIONS. IT WAS NOT DESIGNED, TESTED OR RECOMMENDED FOR THIS USE.• DO NOT USE THIS PRODUCT IN HAZARDOUS LOCATIONS (E.G. EXPLOSIVE ATMOSPHERES). IT WAS NOT DESIGNED, TESTED OR RECOMMENDED FOR THIS USE.• ENSURE THE PRODUCT IS PROPERLY CONNECTED TO THECORRECT POWER SUPLLY FOR THE APPLICATION. REFER TO THE SPECIFICATIONS AND WIRING DIAGRAMS IN THIS MANUAL.E59-M18A108D01-D1PPAB C D EF GHINTRODUCTIONThe iProx is a ﬁ eld programmable inductive proximity sensor from Eaton featuring Cutler-Hammer’s exclusive microprocessor-controlled SmartSense™ technology. This allows the iProx to perform unique sensing functions at extended ranges.If required by your application, the sensing characteristics of the iProx can be modiﬁ ed by using a Microsoft Windows-based software application called ProxView (E59SW1) and a programming accessory (E59RP1 or E59TP1). In addition to adjusting sensing range and outputs, the software can be used to enable certain advanced sensing features disabled by default, such as band sensing, output delays and speed detection. For more detailed programming information, review the ProxView Software User Guide (P50228). This software can be freely downloaded from /iprox. Programming is not required. The iProx is shipped from the factory with default settings that are optimized for most applications.Special versions of the iProx sensor, such as ChipMaster and SpeedSense, come pre-programmed from the factory to fulﬁ ll advanced application requirements without the need to program. These sensors can also be programmed using the ProxView software package.Warning: The iProx sensor is a ﬁ eld programmable sensor with several conﬁ gurable parameters. As such, do not use the iProx without testing the conﬁ guration prior to use. Failure to do so could result in an unsafe condition. MOUNTINGThe iProx is available in both shielded (embedded cap) and unshielded (exposed cap) versions. Mounting instructions for shielded and unshielded sensors are different.Shielded sensors can be fully embedded or ﬂ ush-mounted in surrounding metal.Unshielded sensors typically require a metal-free zone surrounding the sensor cap. (See the ﬁ gure below for dimensions.) However, the Background Metal Rejection feature of the iProx allows even unshielded sensors to be mounted in a metal-rich environment. In most cases, enabling Background Metal Rejection will reduce the sensing range. Consult the ProxView Software User Guide (P50228) for more information.METAL-FREE ZONE DIMENSIONSAB Unshielded Sensor 1.5 x Sensing Range Cap Height Shielded SensorSPECIFICATIONS2-Wire AC Sensors3-Wire DC Sensors Input Voltage20-132 VAC6-48 VDCLoad Current5-500 mA, 5-250 mA > 50° CFor all E59-M12... 5-300 mA, 200 mA > 50° C < 500 mA @ 6-30 VDC < 300 mA @ 32-48 VDCVoltage Drop< 10 VAC< 2.5 VDCBurden Current N/A< 15 mAProtection Overcurrent1Auto ResetSwitching Hysteresis< 15% Rated Sensing DistanceRepeat Accuracy Shielded Models: < 1% Rated Sensing DistanceUnshielded Models: < 3% Rated Sensing DistanceSurge Capacity 3 A / 30 msTemperature Range-40° to +158° F (-40° to +70° C)Material of Construction Housing: 303 Stainless Steel; End Bells: Polycarbonate; Face Caps: Ryton®; Cable: AWM Style 20387 (PVC) Vibration10-55 Hz, 1 mm Amplitude, IEC 60068-2-6Shock30 g, 11 mS, IEC 68-2-27Indicator LED360° ViewableEnclosure Ratings NEMA 4, 4X, 6, 6P, 12 and 13 (IP67)2Response Time3Factory Default Mode30 Hz (10 V/m)Shielded (10 V/m)12 mm: 580 Hz; 18 mm: 390 Hz; 30 mm: 240 HzUnshielded (10 V/m)12 mm: 300 Hz; 18 mm: 150 Hz; 30 mm: 90 Hz Side by Side Mode430 Hz (10 V/m)50 Hz (20 V/m)High Noise Immunity Mode10 Hz (> 20 V/m)10 Hz (> 20 V/m)1Overcurrent protection for conductor size 20 AWG is 5 A; 22 AWG is 3 A; 24 AWG is 2 A.2Our products conform to NEMA tests as indicated, however, some severe washdown applications can exceed these NEMA test speciﬁ cations.

解决问题会议场景对话英语作文

解决问题会议场景对话英语作文A Meeting Dialogue":It was a crisp Monday morning as the team gathered around the conference table for their weekly meeting. The air was filled with the gentle hum of laptops and the sound of pens scratching against notepads as the group prepared to tackle the agenda.Alice, the team lead, opened the meeting with a warm smile. "Good morning, everyone. Thank you all for being here today. As you know, we have a few pressing issues to discuss, and I'm confident that together we can find some effective solutions."She glanced down at her notes before continuing. "First on the agenda is the delay we've been experiencing with the launch of our new product line. John, would you please give us an update on where things stand?"John, the project manager, cleared his throat and stood up. "Thanks, Alice. Well, as you all know, we've been facing some unexpected challenges with the manufacturing process. The lead time for a critical component has been longer than anticipated, and that'scaused a cascading effect on our timeline."He paused, gauging the reactions around the table. "I've been in close contact with our suppliers, and they assure me they're doing everything they can to expedite the delivery. However, it's looking like we'll need to push the launch back by at least two weeks."A murmur of concern rippled through the group, and Alice raised her hand to quiet the room. "Okay, let's not panic. John, what steps have you taken to mitigate the impact of this delay?"John nodded. "Well, I've already reached out to our marketing team to adjust the launch plan. We're going to focus on building anticipation through our social media channels and leveraging our existing customer base. Additionally, I've reallocated some resources to ensure we can still meet our pre-launch milestones."Alice considered this for a moment. "That sounds like a good start. What else can we do to minimize the fallout from this delay?"Sarah, the head of operations, spoke up. "I think we should consider offering some kind of early-bird promotion or pre-order incentive. That could help drive sales and offset the impact of the delayed launch.""Excellent idea, Sarah," Alice replied. "Let's task the marketing team with putting together a compelling pre-order campaign. In the meantime, John, keep us posted on the supplier situation, and let me know if there's anything else I can do to help."John nodded. "Will do, Alice. I appreciate the support."Alice turned her attention to the next item on the agenda. "Okay, moving on. The other issue I wanted to discuss is the ongoing challenge we're facing with our customer support team. Emily, I know you've been working to address some of the pain points. Can you give us an update?"Emily, the customer service manager, cleared her throat. "Absolutely, Alice. As you know, we've been struggling to keep up with the volume of inquiries and complaints we're receiving. Our average response time has been steadily increasing, and our customer satisfaction scores have taken a hit as a result."She paused, her brow furrowed. "I've been working closely with the team to identify the root causes and implement some short-term solutions. We've added more staff during peak hours, streamlined our processes, and implemented a new ticketing system to help us better manage the workload."Alice nodded. "That's good to hear. What else do you think we need to do to get this situation under control?"Emily hesitated for a moment. "Well, the truth is, I don't think these temporary fixes are going to be enough in the long run. We need to take a more comprehensive look at our customer support strategy and make some significant changes."She took a deep breath. "I believe we need to invest in a more robust self-service platform, with detailed FAQs, troubleshooting guides, and a knowledge base that our customers can access 24/7. That would help alleviate the burden on our support team and improve the overall customer experience."Alice considered this proposal. "That sounds like a sensible approach. What kind of timeline and resources would be needed to implement something like that?"Emily glanced down at her notes. "Based on my preliminary research, I think we could have the initial phase of the self-service platform up and running within the next three months. It would require a modest investment in both technology and content development, but I believe the long-term benefits would far outweigh the costs."Alice nodded. "Okay, let's make this a priority. Emily, I'd like you toput together a detailed proposal, including a breakdown of the timeline and budget. We'll review it at our next meeting and decide how to proceed."Emily smiled. "Sounds good, Alice. I'll get started on that right away."Alice scanned the room, making eye contact with each team member. "Alright, is there anything else we need to discuss today?"The group was silent for a moment, then David, the finance manager, raised his hand. "I do have one other item I'd like to bring up, ifthat's okay."Alice nodded. "Of course, David. Go ahead."David cleared his throat. "Well, as you all know, we've been working hard to stay within our budgetary constraints, but I'm starting to see some concerning trends in our expense reports. I'd like to schedule a separate meeting to go over the numbers in more detail and discuss potential cost-saving measures."Alice considered this request. "That's a good idea, David. Why don't we set aside some time later this week to dive into the financials? In the meantime, please share your initial findings with the team so we can all be aware of the situation."David nodded. "Will do, Alice. I'll send out a meeting invite and get the relevant materials prepared."Alice glanced around the room once more. "Alright, unless anyone has anything else to add, I think that's all for today. Thank you all for your hard work and dedication. I'm confident that by working together, we can overcome these challenges and continue to drive our business forward."The team members began to gather their belongings and file out of the conference room, already discussing the next steps and brainstorming potential solutions. Alice watched them go, a small smile playing on her lips. She knew that with this group of talented and committed individuals, there was no problem they couldn't solve.。
