Abstract:
Approaches for stability design of steel frames include the traditional and the modified effective length methods and the notional load approach. This paper presents a storey-based stability factor approach in which storey slenderness and a stability coefficient for a storey are defined, the stability of a storey is checked as a whole. Also presented are detailed comparison of the modified effective length approach, the notional load approach and the proposed storey-based method with FEM. Seven frames, with different bases or beam-to-column connections, one or two spans, one or two stories, with or without leaning columns, uniformly or unevenly loaded, are analysed. Various imperfections are considered. All frames are assumed to be axially loaded to serve as benchmark problems for checking the priority of available methods. It is found that the notional load approach is ideal for frames that are uniformly loaded, and if the modified effective length factors of columns are within 1∼2. The modified effective length is not accurate enough in considering the inter-column interaction of a storey failing in an elastic-plastic state. The proposed storey-based stability factor approach shows good agreement with FEM for all the frames analysed.

Abstract:
The adsorption behaviour of three aromatic acids [phenol, benzoic acid (BCA) and 2-naphthalene sulphonic acid (2-NSA)] and of one aromatic base (aniline) on an aminated macroreticular adsorbent (NDA103) were investigated employing single or binary batch systems at 293 K and 313 K, respectively. All the adsorption isotherms in the studied systems could be adequately fitted by the Langmuir model, thereby indicating the existence of an exothermic adsorption process for phenol, BCA and aniline. At low equilibrium concentrations, the individual uptakes in the single-component systems were higher than those in binary-component systems because of competition between the two types of adsorbate molecules towards the adsorption sites. On the other hand, it is noteworthy that the total molar uptakes of adsorbates in the binary-component systems at high equilibrium concentrations were larger than the uptakes in the single-component systems. In binary-component systems, a large excess of aromatic acids was noted on the adsorbent surface at saturation, presumably as a result of a cooperative effect arising primarily from acid–base interaction between the loaded adsorbates.

Abstract:
Pseudolatex is colloidal dispersion containing spherical solid or semisolid particles and can be prepared from any existing thermoplastic water-insoluble polymers. It is useful for drug encapsulation and controlled drug release. In this study, pseudolatex base was prepared from STR 5L block rubber. The various parameters such as speed and time of homogenization, type and concentration of surfactants, amount of mineral oil, and type of drug loading were studied to prepare the stable pseudolatex. These preparations were evaluated in particle size, pH, viscosity, emulsion stability, drug encapsulation, and in vitro drug release. It was found that the most stable formulation contained 3.5% block rubber, 0.2% methyl cellulose, 6% mineral oil, 4% dibutyl phthalate, 2% sodium lauryl sulfate, and 2% Uniphen P-23 using the speed and time of homogenizer as 20000 rpm and 20 minutes, respectively. Furthermore, the pseudolatex bases reduced the protein impurity form 0.5516% to 0.2108% in formulation with mineral oil and to 0.1781% in formulation without mineral oil, that could decrease contact allergy caused by the protein allergens. Dichloromethane residues in pseudolatex bases were 22.05 mg/L and 7.85 mg/L in formulations with and without mineral oil, respectively, that were satisfied from USP recommendation value of lower than 600 mg/L. Propranolol HCl, lidocaine HCl, and indomethacin could be loaded into pseudolatex only in the concentration of 1%. However, lidocaine base in the concentration of 1-5% could be loaded into pseudolatex which had the similar physical properties and stability to pseudolatex base. The in vitro drug release from pseudolatexs provided the controlled drug release for more than 24 hr.

Abstract:
This project investigated how kairomone lures, camera traps, and counting software could together contribute to pest management. Images of cumulative daily catch of New Zealand Flower Thrips (NZFT) attracted to a ripe peach lactone (6-pentyl-2H-pyran-2-one; 6-PAP) were automatically loaded to the internet and compared with scanned bases checked weekly using in-house software and manual counting. Camera traps were able to provide thrips counts equivalent to delta traps, but daily and remotely. An 11-fold greater NZFT count occurred within 24 h in passive traps after polyethylene sachets loaded with 250 mg of 6-PAP were placed in trees. Intensive trapping, by placing 1, 2, 4, and 8 traps per tree (500 mg/trap), resulted in a maximum 32-fold increase in thrips per tree. While 6-PAP has proved to be a useful tool for monitoring NZFT numbers, our results suggest that it is not likely to be suitable for mass trapping. Future research should investigate NZFT behavior to better understand population movement on an area-wide basis. Camera traps can be a valuable tool for recording insect flight activity remotely, but the number of traps required for statistically reliable estimates may be prohibitive.

Abstract:
The concentration of different toxic metals has increased beyond environmentally and ecologically permissible levels due to the increase in industrial activity. More than 100 million people of Bangladesh and West Bengal in India are affected by drinking ground water contaminated with arsenic and some parts of India is also affected by poisoning effect of copper, cadmium and fluoride. Different methods have been evolved to reduce the arsenic concentration in drinking water to a maximum permissible level of 10 μg/L where as various methods are also available to separate copper from drinking water. Of the proven methods available today, removal of arsenic by polymeric ion exchangers has been most effective. While chelating ion exchange resins having specific chelating groups attached to a polymer have found extensive use in sorption and pre concentration of Cu2+ions. Both the methods are coupled here to separate and preconcentrate toxic metal cation Cu2+and metal anion arsenate(AsO4–) at the same time. We have prepared a series of low-cost polymeric resins, which are very efficient in removing copper ion from drinking water and after coordinating with copper ion they act as polymeric ligand exchanger, which are efficiently removing arsenate from drinking water. For this purpose Schiff bases were prepared by condensingo-phenylenediamine witho-,m-, andp-hydroxybenzaldehydes. Condensing these phenolic Schiff bases with formaldehyde afforded the chelating resins in high yields. These resins are loaded with Cu2+, Ni2+2+, and Fe3+ions. The resins and the polychelates are highly insoluble in water. In powdered form the metal ion-loaded resins are found to very efficiently remove arsenate ion from water at neutral pH. Resins loaded with optimum amount of Cu2+ion is more effective in removing arsenate ions compared to those with Fe3+ion, apparently because Cu2+is a stronger Lewis acid than Fe3+. Various parameters influencing the removal of the arsenate ion from drinking water to a concentration level below 20 μg/L are studied.

Abstract:
Abstract Natural halloysite clay nanotubes were used as a template for clay/Ru core-shell nanostructure synthesis. Ru-nanoparticles were produced via a ligand-assisted metal ion intercalation technique. Schiff bases formed from different organic compounds proved to be effective ligands for the metal interfacial complexation which then was converted to Ru particles. This produces a high amount of intercalated metal nanoparticles in the tube’s interior with more that 90% of the sample loaded with noble metal. Depending on the selection of organic linkers, we filled the tube’s lumen with 2 or 3.5-nm diameter Ru particles, or even larger metal clusters. Produced nanocomposites are very efficient in reactions of hydrogenation of aromatic compounds, as tested for phenol and cresols hydrogenation.

Abstract:
Abstract Objective This study aimed to assess the effect of reinforcement, denture base thickness, and acrylic resin types on dynamic and static fracture strength in mandibular implant overdentures with bar attachment. Materials and Methods One hundred and eight experimental mandibular implant overdentures with bar attachments were fabricated in three main groups, namely unreinforced (control: C), reinforced with unidirectional glass fibers (FR), and Co–Cr cast metal (MR). Each group included denture bases of 2-, 3-, and 4-mm thicknesses and produced with conventional (CA) and high-impact acrylic (HIA) resins. Specimens were thermocycled (5,000 times, 5–55°C) then subjected to a 400,000 cyclic load regime. Unbroken specimens were then loaded until fracture by a universal testing machine. Differences in mean fracture resistance among the groups were compared using the one-way analysis of variance (with post hoc Tukey's honestly significant difference test) and Student's t-tests (α = 0.05). Results Fracture strength increased significantly when the denture base thickness was increased (p = 0.001). The 2-mm denture base thickness was not enough for reinforcement. The fracture strength of the FR groups was significantly higher than other groups for 3- and 4-mm thicknesses (p = 0.001). The fracture strength of the HIA resin was significantly higher than CA resin in FR groups (p = 0.029 and p = 0.001). MR groups showed the weakest fracture strength. Conclusions The 2-mm denture base thickness had sufficient fracture strength without reinforcement and a positive relationship between acrylic resin thickness and fracture resistance was found.

Abstract:
Les défauts d’arcs électriques sont souvent la cause du déclenchement d’un incendie dans l’habitat. Les détecter constitue une amélioration de la sécurité électrique domestique. La contribution de cette thèse porte sur la problématique de l’identification et de la détection de défauts d’arcs électriques sur le réseau basse tension domestique (charge simple et combinée). Dans ce travail de thèse, le premier axe de recherche porte sur la mise en œuvre d’un modèle de simulation de réseau. Sur le modèle de réseau l’objectif est d’introduire à volonté et de manière graphique des charges de nature différentes associées à un défaut d’arc électrique série. La modélisation porte sur la source de tension, des charges domestiques, le défaut d’arc et le bloc d’analyse numérique du courant et de la tension pour la commande d’un disjoncteur. Le second axe de recherche porte la mise au point de méthodes de détection robuste d’un défaut d’arc électrique Quatre méthodes originales de détection portant sur la tension et le courant de ligne ont été développées dans le cadre de ce travail de thèse. Elles sont toutes basées sur l’analyse des caractéristiques fréquentielles et temporelles du courant de ligne. Toutes les méthodes produisent une information dont l’amplitude tend à s’accroître en présence d’un arc électrique. Toutefois, le caractère non déterministe et très variable des signaux produits par un arc électrique ainsi que la grande variabilité des charges et des perturbations qu’elles introduisent rendent la détection très difficile. L’ensemble des études s’est donc systématiquement composé d’une comparaison entre la situation avec et sans arcs. Le résultat a abouti à une approche combinée de plusieurs méthodes et d’un modèle simple de décision basé sur un simple seuil. Un prototype implémentant une partie de l’algorithme a montré la faisabilité d’un circuit en temps réel
The electrical arc faults are the cause of electrical home fire. Detecting them is an improvement of domestic electrical safety. The thesis contribution focuses on the problem of the electrical arc fault identification and detection in the domestic low voltage network. In this thesis, the first research objective is the modeling of a domestic electrical network. The aim of the modeling is to recreate graphically the loads and the topology of the real domestic electrical network associated with a series electrical arc fault. The modeling is made on the AC voltage source, domestic loads, arc fault model and a block of current and voltage analysis to control a circuit breaker. The second research objective is the development of a robust method for detecting arcing fault. Four detecting methods were developed as part of this thesis; they are based on the current analysis of frequency and time characteristics. All methods generate information whose amplitude tends to increase in the presence of an electric arc. However, the non-deterministic and random feature of the signals produced by the electrical arc fault as well as the large number and variability of loads and the disturbances which they introduce make the arc detection very difficult. All the studies consistently are composed of a comparison between the normal operation and arc fault signals. The result has resulted in a combined approach of some methodologies and a simple decision model based on a threshold. A prototype which contains a part of the algorithm was shown the feasibility of a circuit in real time

Acyclovir是一個合成的非環性衍生物,具有抗疹病毒的作用。Acyclovir 需經疹病毒特有的酵素作用後,才能轉化為其活化型-Acyclovir三磷酸鹽, 此活化型可藉由抑制病毒DNA聚合合成及干擾病毒DNA的複製,而達到抗 病毒的作用。 本論文共分為二個部份: 第一部分:兩種口服劑型之生體相等性比較 本研究是比較兩不同廠牌acyclovir 800mg口服錠劑,利用人體試驗所得之 血中濃度,而求得兩劑型之藥物動態學參數(如AUC、Cmax、Tmax及、T1/2等), 經統計方法來得知兩者之間是否具有生體相等性。 實驗之設計為一開放式隨機交叉試驗,過程分兩階段,共有八名受試者。 血漿檢品經去蛋白法處理後,再利用高效能液相層析法來定量acyclovir的血漿 中濃度。 實驗中所選擇之分析方法經同日內、異日間精確度及最低定量濃度試驗, 顯示此方法具有良好的線性關係,且再現性及穩定性亦佳。經人體試驗的結果顯 示,acyclovir在人體的口服吸收具有高變異性;對於此兩不同廠牌的acyclovir 錠劑(Sinphar Acyclovir錠及Zorivax錠),藥物的口服吸收都很快(到達最高血中 濃度的時間約為1.6小時),且具有相近的最高血中濃度值;利用電腦軟體所得之 平均AUCpartial分別為3.28 ?0.8 mg*hrs /L及3.42 ?1.1 mg*hrs /L,平均AUCtotal 分別為4.19 ?1.5 mg*hrs /L及3.98 ?0.8 mg*hrs /L,所得之結果和許多文獻都很 相近。 所得藥物動態學參數經對數轉換後,利用ANOVA檢定,可知Cmax、Tmax、 AUCtotal、AUCpartial、T1/2等在統計上並無顯著差異(p>0.05),而利用two one- sided t-test亦可得兩處方之藥物動態學參數大致符合80%-125%信賴區間,由此 證明此兩藥品具有生體相等性。 第二部份:以複因子試驗設計法探討含acyclovir微球之製備 Acyclovir是一個人體口服生體可用率很低,吸收比例會隨著劑量增加而降 低的藥物;且其口服吸收很快,半衰期只有4小時,因此一天需服藥多次。基於 以上的原因,我們希望利用微粒包覆法來製備含acyclovir微球,而能達到延緩 藥物釋出的目的。 我們選用油/水溶劑揮發法做為微粒包覆的製備法,並利用23複因子試驗設 計法,選擇乙基纖維素黏度(100cp或45cp),乙基纖維素/acyclovir比例(2/1或 1/1,w/w)及二氯甲烷/乙基纖維素比例(20x或15x,v/w)為三個實驗因子,探 討這些因子的主效應及交感效應對acyclovir在人工胃液及人工腸液中十二小時 後的溶離量及藥品包覆效率的影響。 實驗中利用示差掃描熱分析儀,庫爾特粒徑分析儀,掃描式電子顯微鏡來 觀察微球的物理化學性質;根據美國藥典之規定,進行人工胃液及人工腸液溶離 試驗;並選擇其中一種處方及未經包覆之acyclovir乾粉,進行在三個不同溫度(25 ℃,37℃,50℃)下三個月的安定性試驗。 利用此製備法可得粒徑約數十微米,表面具有孔洞之微球;此法所得之微 球具有良好的再現性且不會改變acyclovir之熱力學性質。根據複因子試驗設計 的結果,提高乙基纖維素黏度及二氯甲烷/乙基纖維素比例、降低乙基纖維素 /acyclovir比例可以得到較佳的包覆效率;若要得到較理想的十二小時溶離結果, 則應選用高黏度的乙基纖維素,及較低的乙基纖維素/acyclovir比例及二氯甲烷/ 乙基纖維素比例。最後,三個月的安定性試驗結果發現,和未經包覆之藥品比較 之下,用乙基纖維素將acyclovir包覆,確可有效地降低acyclovir的分解速率, 達到提高藥品安定性的目的。 經本實驗結果顯示,利用油/水溶劑揮發法進行微粒包覆為一可行的方法, 且利用高分子聚合物對藥物進行包覆,在體外溶離試驗的確可以達到延緩藥物釋 出的目的,但是在體內實際的狀況及是否真能提高體內的吸收比例,則必須再進 行更進一步的動物試驗及人體試驗才可得知。 This thesis is composed of two parts: Part I:A Bioequivalence Study on Two Acyclovir Oral Formulations Part II:Factorial Experiment Based Preparation of Acyclovir-Loaded Ethyl Cellulose Microspheres Part I:A Bioequivalence Study on Two Acyclovir Oral Formulations Acyclovir is an acyclic nucleoside analogue of guanosine which is a potent and selective antiviral agent. It exhibits its antiviral effect on herpes simplex virus (HSV) and varicella-zoster virus by interfering with DNA synthesis and inhibiting viral replication. Bioequivalence studies investigate and compare pharmacological characteristics of different formulations of a drug in terms of the rate and extent of absorption of active ingredients. The purpose of bioequivalence trials is to identify pharmaceutical equivalents or pharmaceutical alternatives that are intended to be used interchangeably for the same therapeutic effect. In the present study, bioequivalence between two acyclovir oral formulations were evaluated based upon pharmacokinetic responses such as AUC, Cmax, and Tmax. These responses were determined from the plasma concentration-time curve, and the plasma acyclovir concentrations were measured by an HPLC method with fluorescence detection. The study was carried out according to a two-way randomized cross-over single dose design. The pharmacokinetic parameters of acyclovir via oral administration showed generally high variability. After oral administration of 800mg acyclovir tablets, absorption from the GI tract was rapid with both formulations and led to similar peak plasma levels. The mean Tmax values were observed at about 1.6 hours after administration of both the reference and the test tablets. The mean AUC was 3.28?.8 mg*hr/L and 3.42?.1 mg*hr /L, respectively. The data obtained in the present study agrees well with the literature data. According to the results of ANOVA statistics and the 90% confidence intervals obtained by the log transformations, the area under the plasma concentration-time curves and the peak concentrations obtained from the two acyclovir tablets are equivalent as indicated by the formulation effect. Part II:Factorial Experiment Based Preparation of Acyclovir-Loaded Ethyl Cellulose Microspheres Absorption of acyclovir from the GI tract is fast and incomplete. Increasing the contact time of orally administered acyclovir with the absorption area produced a marked increase in bioavailability. The technique of microencapsulation can be used as an effective method in the preparation of oral sustained-release dosage form. The purpose of this study was to investigate the feasibility of preparing sustained release microspheres of acyclovir, a water-soluble drug, by solvent evaporation method using an external aqueous phase, and ethyl cellulose was used as the wall polymer. Factorial experiment is the application of statistical principles for data collection and analysis. A designed experiment introduces systematic changes into the variables of a system with the objective of discovering which variables are responsible for the observed changes. Factorial experiment was usually utilized for formulation optimization purposes. A 23 full factorial experiment was used to study the effect of the selected variables on the loading of the microspheres and the dissolution characteristics in the simulated gastric fluid (SGF) and simulated intestinal fluid (SIF). The independent variables were: polymer viscosity, polymer/drug ratio, and organic solvent / polymer ratio. Optimization were performed in order to maximize the loading efficiency and the fraction of acyclovir release after 12 hours in both dissolution media. The physicochemical state of the drug in these formulations was determined by using differential scanning calorimetry (DSC), Coulter counter, and scanning electron microscopy (SEM). The acyclovir content of the microspheres was determined by HPLC assay after extraction with CH2Cl2. The stability experiments under three temperatures were also performed to study the degradation properties of acyclovir-loaded ethyl cellulose microspheres in order to evaluate the possibility of the protection of acyclovir from degradation by microencapsulation. In conclusion, o/w solvent evaporation method used in this study is suitable for the preparation of acyclovir-loaded ethyl cellulose microspheres. The release rate of acyclovir from the microspheres depends on the formulation variables, with significant interaction between these variables. The optimized release fraction after 12 hours was obtained at high polymer viscosity, low polymer/drug ratio, and low organic solvent / polymer ratio. Also, the microspheres prepared in the study demonstrated good protective effect of acyclovir from degradation.

Because the limitations of hardware, a streaming server has the limitation of its service. In order to provide the scalability, the system provider must build a group of large servers to serve the customers. This thesis provides the implementation of a load distributed server based on RTSP. In this system, the master server uses the “303 See Other” response in RTSP to redirect the clients. Using the mechanism, we provide a loose architecture for scalable. We also add a monitoring mechanism to make the system reliable. If this system collaborates with smart clients, it can also group the variant servers as our loose architecture of servers. Additionally we make the Darwin Streaming Server can process the MPEG-2 TS file and streaming it. The benefit is to accelerate the clip online. Because the the multimedia owned by content providers are MPEG-2 TS, the system provider can immediately use those files without transcoding.

Abstract:
Electricity consumption always changes according to need. This pattern deserves serious attention. Where the electric power generation must be balanced with the demand for electric power on the load side. It is necessary to predict and classify loads to maintain reliable power generation stability. This research proposes a method of forecasting electric loads with double seasonal patterns and classifies electric loads as a cluster group. Double seasonal pattern forecasting fits perfectly with fluctuating loads. Meanwhile, the load cluster pattern is intended to classify seasonal trends in a certain period. The first objective of this research is to propose DSARIMA to predict electric load. Furthermore, the results of the load prediction are used as electrical load clustering data through a descriptive analytical approach. The best model DSARIMA forecasting is ([1, 2, 5, 6, 7, 11, 16, 18, 35, 46], 1, [1, 3, 13, 21, 27, 46]) (1, 1, 1)48 (0, 0, 1)336 with a MAPE of 1.56 percent. The cluster pattern consists of four groups with a range of intervals between the minimum and maximum data values divided by the quartile. The presentation of this research data is based on data on the consumption of electricity loads every half hour at the Generating Unit, the National Electricity Company in Gresik City, Indonesia.

Abstract:
Korea Atomic Energy Research Institute (KAERI) has been developing a conceptual design of the demonstration fast reactor (DFR), which is the pool type sodium cooled fast reactor with the thermal power of 1548.2 MW and the core loaded with metal fuel. The DFR is composed of a Primary Heat Transport System (PHTS), an Intermediate Heat Transport System (IHTS), a Steam Generating System (SGs) and a decay heat removal system (DHRS). The DHRS is composed of 2 units of Passive Decay-heat Removal Circuits (PDRC) and 2 units of Active Decay-heat Removal Circuits (ADRC). The PDRC consists of two independent loops with sodium-to-sodium Decay Heat eXchanger (DHX) and natural-draft sodium-to-Air Heat eXchanger (AHX). The ADRC consists of two independent loops with sodium-to-sodium DHX and Forced-Draft sodium-to-air Heat eXchanger (FDHX) located in the upper region of the reactor building. The PDRC is very different from that of KALIMER-600 on the points of the submerged location and the heat transfer mechanism. For the identification of safety characteristics, 5 DBE’s (Design Bases Events) are analyzed using the MARS-LMR code. The representative DBE’s are TOP (Transient of Over Power), LOF (Loss Of Flow), LOHS (Loss Of Heat Sink), Reactor Vessel Leak and Pipe Break. As a result, it is identified that the DFR were appropriately performed as designed and the temperatures of the fuel and the structure were evaluated to satisfy the criteria.

Abstract:
With the advent of electronically alterable memories in electronic gas turbine engine control systems, there is now the opportunity for updating software in the field. Field loading provides a means to economically correct problems or introduce enhancements to system operation through the electronic control. In this paper we describe the characteristics of high integrity reprogramming systems used to update engine controls in-the-field. Pratt & Whitney Aircraft supports two methods for in-service reprogramming of Electronic Engine Controls (EECs), These two methods are PC Laptop based loaders and ARINC loaders. This discussion will focus on the capabilities provided to support in-the-field reprogramming of engine controls. The flexibility, integrity, and the benefits of field reprogramming provided by these software loading systems will be explained. These reprogramming systems provide a PC based application and ARINC based systems for either on-wing reprogramming or on-board reprogramming directly from a flight deck device to the EEC. The PC Loader reprogramming utilities allow field personnel to reprogram engine control application software and/or constants and configuration information using a suitably equipped IBM PC or compatible computer. These utilities are intended to be operated per Service Bulletin authorization only. They require a PC compatible computer (presumably a laptop model) with 2 UART interface cards, an interfacing cable, and the new software to be loaded. The rigor and manner of the integrity checks to ensure proper loading of the control is essential to an acceptable loading system. There are two types of ARINC-based loaders: on-wing loaders and on-board loaders. Both types enable the operator to upload application, trim, and/or configuration software to the engine control. Additionally the ARINC 615 device allows operators to download fault and configuration data from the control. Each type of loader uses a specially formatted file to control the sequence of operations involved in a data loading session. The on-wing loader utilizes a specially designed portable data loader which connects directly to the EEC via dedicated cabling through the control’s ARINC connectors. This type of data loader contains software which communicates via an ARINC 615 protocol to a peer software entity running on the EEC. The on-board loader uses the aircraft’s central maintenance computer system to communicate with the EEC over the aircraft’s ARINC 629 data bus. It also operates using a peer-to-peer communication protocol with the EEC. The ARINC 629 loader requires no extra equipment or cabling, nor does it require the EEC to be accessible for attachment of cables.

Abstract:
The systematization of adaptive friction clutches of all types and generations on the basis of rated load capacity and accuracy of operation is carried out. The systematization allows us to divide all the variety of designs of adaptive friction couplings at groups with particularly high accuracy and low nominal loading capacity, with average accuracy and the rated load capacity and low accuracy and high load capacity. The carried out systematization allows to define areas of rational application of groups of adaptive friction clutches.

Abstract:
The main provisions of the method for selecting the form of the load characteristic of the AFM with a separate power circuit are formulated. The method involves taking into account the nominal load, the total mass of the drive, the value of the gain of the adaptive friction clutch with a separate power circuit and the accuracy of its operation, as well as recommendations for the choice of the second design version of the clutch. The choice of the type of adaptive friction clutch, taking into account the load characteristics, is based on the different load capacity and accuracy of operation, which correspond to these forms.

Abstract:
Deep tissue injury (DTI) is a serious pressure ulcer, characterized by necrotic tissue mass under intact skin. There is evidence that elevated tissue strains/stresses over prolonged times cause DTI, via paths of physical damage to cells, ischemia and impaired diffusion. Skeletal muscle is considered less tolerable to mechanical loads, likely because of higher metabolic demand and denser vascularization. When damaged in compression, muscle tissue stiffens up to ∼3-fold, depending on the magnitude and duration of loading [1]. Cell-death thresholds for loaded muscle, that are a Boltzmann-type downward-step sigmoid function of the magnitude of compression strain/stress and time, were developed based on meta-analysis of animal experiments [2]. These cell-death thresholds allow extrapolation of biological damage trends from computational stress analyses of muscle in load bearing postures.

Full text
Abstract:
Film cooling experiments were run at the high speed cascade wind tunnel of the University of the Federal Armed Forces Munich. The investigations were carried out with a linear cascade of highly loaded turbine blades. The main targets of the tests were to assess the film cooling effectiveness and the heat transfer in zones with main flow separation. Therefore the blades were designed to force the flow to detach on the pressure side shortly downstream of the leading edge and it reattaches at about half of the axial chord. In this zone film cooling rows are placed among others for reduction of the size of the separation bubble. The analyzed region on the blade is critical due to the high heat transfer present at the leading edge and at the reattachment line after main flow separation. Film cooling can contribute to a reduction of the size of the separation bubble reducing aerodynamic losses but increases in general heat transfer due to turbulent mixing. The reduction of the size of the separation bubble might also be twofold since it acts like a thermal insulator on the blade and reducing the size of the bubble might lead to stronger heating of the blade. Film cooling should therefore take into account both: firstly a proper protection of the surface and secondly reduce aerodynamic losses diminishing the extension of the main flow separation. The overall effectiveness of film cooling for a real engine has to combine heat transfer with film cooling effect. In this paper the overall effectiveness of film cooling, combining results from measurements of the adiabatic film cooling effectiveness and the local heat transfer coefficient are shown. The tests comprise the analysis of the effect of different outlet Mach and Reynolds numbers at engine relevant values and film cooling ratio. A new parameter is introduced which allows to evaluate the effect of film cooling accounting at the same time for the change of local heat transfer coefficient. To the authors’ opinion this parameter allows a better, physically based assessment than the strategy using the so-called heat flux ratio. A parameter study is carried out in order to benchmark the effect of changes of the blade design.

Abstract A fuzzy-based optimal delivery scheduling approach is introduced in this research. In this approach, optimal delivery scheduling is conducted at three different levels considering (1) one driver and one load, (2) one driver and multiple loads, and, (3) multiple drivers and multiple loads. Fuzzy-based clustering methods are employed to classify delivery tasks into driver groups, load groups, and location groups. The optimal sequence and timing parameters of the delivery tasks are identified using the fuzzy-based clustering results and state-space search. The intelligent optimal delivery scheduling system was implemented using Smalltalk.

Full text
Abstract:
This technical report documents the second of a two-phase research and development (R&D) study in support of the development of a combined Load and Resistance Factor Design (LRFD) methodology that accommodates geotechnical as well as structural design limit states for design of the U.S. Army Corps of Engineers (USACE) reinforced concrete, hydraulic navigation structures. To this end, this R&D effort extends reliability procedures that have been developed for other non-USACE structural systems to encompass USACE hydraulic structures. Many of these reinforced concrete, hydraulic structures are founded on and/or retain earth or are buttressed by an earthen feature. Consequently, the design of many of these hydraulic structures involves significant soil structure interaction. Development of the required reliability and corresponding LRFD procedures has been lagging in the geotechnical topic area as compared to those for structural limit state considerations and have therefore been the focus of this second-phase R&D effort. Design of an example T-Wall hydraulic structure involves consideration of five geotechnical and structural limit states. New numerical procedures have been developed for precise multiple limit state reliability calculations and for complete LRFD analysis of this example T-Wall reinforced concrete, hydraulic structure.

Full text
Abstract:
The U.S. Army Corps of Engineers (USACE) currently operates and maintains approximately 193 commercially active lock sites with 239 locks and dams spanning nearly 12,000 miles. These networks of water channels are used to transport 600 million tons of domestic cargo, generating $405 billion in revenue annually. Nearly 60% of these structures in operation are over 50 years old and have reached design life. A failure of the miter gates could result in a major negative impact on the economy and on the ability to maintain flood control. Administrators need recommendations to better prioritize maintenance and repair of the USACE miter gates. This work investigated the influence of miter gate’s quoin block degradation on load transfer to the pintle and/or pintle connections. Results of finite element analysis are reported for the quoin block degradation simulated levels of 0%, 25%, 50%, and 75%. The parametric study shows the overstressed regions are the pintle neck and bolt-hole regions. To improve pintle designs so they may better mitigate detrimental environmental based deterioration effects, this work recommends (1) increasing the thickness of the bolt-hole connection region and (2) adding ribbing reinforcement around the neck area of the pintle.

STUDY ON FORCE MECHANISM OF CABLE-TRUSS FRAME AND JUMPED LAYOUT OF ANNULAR CROSSED CABLE-TRUSS STRUCTURE. The Hong Kong Institute of Steel Construction, September 2021. http://dx.doi.org/10.18057/ijasc.2021.17.3.3.

Full text
Abstract:
A new type of cable-strut tension structure named Annular Crossed Cable-truss Structure(ACCTS) comprises a series of planar cable-truss frames crossed each other. To investigate the force mechanism of ACCTS, a cable-truss frame model with 2-bar and 6-cable has been developed, and its initial stiffness formula has been derived as well. The model is further simplified to make it is upper and lower vector heights equal, and then the initial stiffness formula and the critical slack load formula are further deduced. Based on ANSYS software and cable-truss frame with a span of 60m, the influences of the number of struts and position of jumped layout on the cable-truss frame are studied. According to the former 60m span cable-truss frame's research results, the jumped layout of ACCTS with a span of 100m is studied. The static and dynamic performances of two schemes, the optimal jumped layout scheme and the original scheme, are systematically studied. It is shown that the number of struts would be about 6~8 for the planar cable-truss frame and the optimal order of jumped layout is strut 6-7→strut 4-5→strut 2-3. The optimal order of jumped layout of ACCTS agrees with that of the cable-truss frame, verifying the feasibility of conclusions. In the condition of no variation in the original structure's static and dynamic performance, the optimal scheme of the jumped layout will lower the steel consumption and enhance the buckling loads. Moreover, it also simplifies structure for easy construction.
