Piles embedded in p-y sand below water table subjected to static loading-sensitivity investigations.

Laterally loaded pile is a complex system involving pile-soil interaction which is dependent on a number of parameters. The design process of laterally loaded pile is lengthy and at times obscure. This study aims at visualizing this process and relating performance of the pile to the design variables through sensitivity analysis. Short as well as long single piles, both hinged and fixed, embedded in sand, under different range of lateral static loads have been studied. Pile groups have also been studied. The behaviour of the pile is modeled by means of one dimensional beam element. The adjacent soil is simulated by means of p-y model developed by Cox, Reese and Grubbs (1974). The maximum kinematic quantities of the pile-soil system being of crucial importance according to the serviceability limit state design criteria are subjected to sensitivity analysis assessment. The performance functional that involves the maximum generalized deformations is formulated based of the virtual work principle.

Testing of Level Shifters in Multiple Voltage Designs

The use of multiple voltages for different cores is becoming a widely accepted technique for efficient power management. Level shifters are used as interfaces between voltage domains. Through extensive transistor level simulations of resistive open, bridging and resistive short faults, we have classified the testing of level shifters into PASSIVE and ACTIVE modes. We examine if high test coverage can be achieved in the PASSIVE mode. We consider resistive opens and shorts and show that, for testing purposes, consideration of purely digital fault effects is sufficient. Thus conventional digital DfT can be employed to test level shifters. In all cases, we conclude that using sets of single supply voltages for testing is sufficient

Contact stresses in conical shaped rollers

This document has developed both the strategy and equations necessary to understand the stress distribution when two conical shaped rollers come into contact, both over their contact surface region and inside the material. One of the most important findings of this thesis is that when two conical rollers push against one another, the resulting contact patch takes a trapezoidal-like shape due to the geometry of the cone and the type of loading. As a direct result of the geometry of the cone, the contact patch is smallest at the smallest cross-sectional area and largest at the largest cross-sectional area. Nevertheless, the stress magnitude is largest at the smallest cross-section and gradually decreases until it reaches the smallest stress value at the largest cross-section. The maximum stress on the cone\u27s surface is located at the center of the contact patch of a given section. As the measured points move away from the center of the contact patch, the stress distribution across the contact patch gradually drops. Once the measured points are outside the contact patch, where the distance from the center of the contact patch is greater that the contact patch half-width, the stress distribution takes an abrupt change. This change will drop until eventually the measured stress reaches zero when points are calculated a fair distance away from the contact region

The role of the Civil and Commercial Court of Qatar Financial Centre under the New Arbitration Law No. 2 of 2017

أنشئت المحكمة المدنية والتجارية لمركز قطر للمال (محكمة مركز قطر للمال) بموجب قانون مركز قطر للمال رقم 7 لسنة 2005 و تعديلاته. وتختص المحكمة نوعيا بمسائل محددة، حيث تختص الدائرة الإبتدائية بالمحكمة دون غيرها بالفصل في جميع الدعاوى و المنازعات المدنية والتجارية التي يكون أحد أطرافها شركة من الشركات المرخصة من قبل هيئة مركز قطر للمال، بينما تختص الدائرة الإستئنافية بالمحكمة بالفصل في الطعون المقامة أمامها في الأحكام الصادرة عن الدائرة الإبتدائية. و بصدور القانون رقم 2 لسنة 2017 بإصدار قانون التحكيم في المواد المدنية و التجارية، أعطى المشرع القطري المحكمة عدة اختصاصات و صلاحيات إضافية تتعلق بتقديم المعاونة و المساعدة القضائية للتحكيم و الرقابه عليه ، و ذلك إذا ما تم إختيارها من قبل الأطراف في إتفاق التحكيم بصفتها المحكمة المختصة بالاشراف و الرقابة على التحكيم الذي يجري في دولة قطر. و بإعطاء الاختصاص للمحكمة المدنية و التجارية لمركز قطر للمال في قانون التحكيم الجديد ، إلى جانب دائرة منازعات التحكيم المدني و التجاري بمحكمة الاستئناف بحسب الاحوال ، ما هو إلا دليل على الرغبة القوية لدى المشرع القطري في ان تلعب المحكمة دورا رئيسيا في التحكيم التجاري الدولي. وقد نص القانون الجديد على إختصاص المحكمة المختصة بأداء بعض الوظائف المتعلقة بتعين المحكم في المواد 11))5 (البندين أ،ب) ، و رد المحكم في المادة 13)1 ،(و الفصل في اختصاص هيئة التحيكم في المادة 16 بند 3 ،ومساعدة هيئة التحيكم في الحصول على الأدلة في المادة 27 بند 1 ،ونظر دعاوى بطلان حكم التحكيم في المادة 3 بند 2The Civil and Commercial Court of the Qatar Financial Centre (“the QFC Court”) was established by virtue of the Qatar Financial Centre Law No. 7 of 2005 as amended by Law No. 2 of 2009 (“the QFC Law”). The QFC Court has limited jurisdiction over specific subject matters. Under the QFC Law, and the QFC Court Regulations and Procedural Rules, the QFC Court has jurisdiction over civil and commercial disputes which arise from transactions, contracts, arrangements or incidences which take place in or from the Qatar Financial Centre and which are between parties that are established in the QFC. The QFC Court will also hear disputes which relate to civil and commercial disputes between a QFC established entity and contractors and/or employees of the QFC entity. In the case of contractors, what this means is that the contractor does not need to be established in the QFC but in fact may be established anywhere in the world. The QFC Court will also hear disputes which involve an entity established in the QFC and an entity established in the State of Qatar. However, under Law No. 2 of 2017 “Issuing the Law of Arbitration in Civil and Commercial Matters” (the “New Arbitration Law”), the QFC Court has been conferred with additional powers to discharge certain supportive and supervisory functions over arbitrations seated in the State of Qatar, only if it is chosen by the parties as the Competent Court in the arbitration agreement. This is an important development as it allows the parties, inter alia, to utilise the QFC Court, which is modelled on leading international commercial courts, in relation to the arbitral proceedings, and to work under procedures similar to those found in common law systems. The QFC Court’s new functions under the New Arbitration Law include the appointment of arbitrators in Articles 11(5)(a) and 11(5)(b), the removal of arbitrators (Article 13(1)), decisions on arbitral jurisdiction (after the tribunal has already decided) (Article 16(3)), assistance in taking evidence (Article 27(1)), and the setting aside of arbitral awards (Article 33(2)). This article examines the jurisdiction of the QFC Court in relation to arbitration under the New Arbitration Law, key differences between the QFC Court procedures and other State Court procedures, and the importance of a well-drafted forum selection clause to confer jurisdiction on the QFC Court

Nanocapsules on a Lipid Membrane

Nanoparticle technology is gaining traction in many different industries, particularly in imaging and the medical industries, and thus it becomes increasing important to understand how particles will affect the body. This is why we want to look at the way nanoparticles interact with lipid membranes, since lipids play vital roles in biological processes such as stabilizing the distal airways in our lungs in low volume situations. Knowing how nanoparticles will interact with these lipids can give us insights into the potentials cytotoxicity of the particles, and how other agents, such as viruses act near/on a lipid membrane. In thisthesis, we look at Nanocapsules, to determine the way they dock and aggregate on a lipid membrane

Dynamic Voltage Scaling Aware Delay Fault Testing

The application of Dynamic Voltage Scaling (DVS) to reduce energy consumption may have a detrimental impact on the quality of manufacturing tests employed to detect permanent faults. This paper analyses the influence of different voltage/frequency settings on fault detection within a DVS application. In particular, the effect of supply voltage on different types of delay faults is considered. This paper presents a study of these problems with simulation results. We have demonstrated that the test application time increases as we reduce the test voltage. We have also shown that for newer technologies we do not have to go to very low voltage levels for delay fault testing. We conclude that it is necessary to test at more than one operating voltage and that the lowest operating voltage does not necessarily give the best fault cover

Frequency Analysis of Annual One Day Maximum Rainfall at Amman Zarqa Basin, Jordan

Water management and design of irrigation and drainage projects are based on extreme values rather than on average values. Annual daily maximum rainfall corresponding to return periods varying from 2 to 100 years is used by design engineers and hydrologists for economic planning, and design of minor and major hydraulic structures. This research aims at performing frequency analysis of annual daily maximum rainfall in Amman-Zarqa Basin (AZB) which is an important basin in Jordan.  Daily rainfall data at 22 stations distributed in Amman-Zarqa Basin with long time series (more than 40 years) were used for this purpose. For each station, the annual 1- day maximum rainfall data were extracted. Daily maximum values have then been statistically analyzed by RAINBOW software using two probability distribution functions, namely: Linear and log normal distributions. The goodness of fit for the selected distributions is tested using the Chi-square and the Kolmogorov–Simrnov tests at three significant levels (?=5%, 10% and 20%). The results of the goodness of fit indicate that the Log normal distribution provides a good fit to the rainfall data in the basin. Frequency analysis is then conducted to extract the magnitude of 1 day annual maximum rainfall corresponding to 2, 5, 10, 25, 50 and 100 yr return periods for the 22 stations in AZB. Analysis of rainfall regime would enhance the management of water to prevent floods and droughts as well as an effective design of drainage structures especially in relation to their required hydraulic capacity.

The main objectives of this study are to determine the chemical and physical characteristics of ground water of Ainsifni Pila Spi aquifer and to asses its quality for determining its suitability for domestics and irrigation purpose and to compare the concentration of both cations and anions with that of WHO. Ground water samples were collected from 8 drilling wells, during field work in Sept. 2014, for the analysis of their chemical composition of major cations and anions. The analysis comprises physical and chemical parameters of ground water such as; EC, pH, TDS, Na, K, Ca, Mg. HCO3, CO3, SO4, CL and NO3. Chemical parameters such as, total hardness (TH), sodium percent (Na%) and sodium adsorption ratio (SAR),  were calculated, based on the analytical results of ground water samples. Basement rocks of the studied area which is crop out at the surface of ainsifni anticline, are represented by Pila Spi Formation of Middle Miocene age which consist of limestone. It is overlain by Quaternary sediments which are highly permeable beds. Hydrochemical analysis are analyzed graphically using Piper diagram to determine the suitability and type of the groundwater. Sodium adsorption ratio (SAR) and sodium percentage (Na%) are also calculated to show the suitability of ground water for agricultural irrigation. According to the results of chemical analysis of ground water samples, types of water are of CaHCO3 and mix Ca-Mg-HCO3. More over ground water samples are of moderate TDS which is within the specification of (TDS) values set up by the WHO, medium TH and generally groundwater of the studied are is of alkalinity in nature. The over all quality of ground water samples of the studied area in most chemical constituents is on the moderate side in comparing with that of WHO due to its unique location away from any behavior of environmental pollutants. Rainfall water is the only source of replenishment to the groundwater aquifer
