Running Head: Analyzing Performance of Islamic and Conventional Funds Listed In Karachi Stock Exchange

The global financial crises of 2009 had a profound impact on international and domestic markets causing liquidity crunches and bailout appeals. It was at this juncture that previously ignored Islamic finance suddenly became a center of attention. Twenty one conventional equity funds and four Islamic equity funds are selected which survived at least for five years from 2009 to 2013.This study focuses on drawing a comparison in performance between open ended Islamic mutual funds and conventional mutual funds. Daily NAVs and dividend payout data are collected from the website of the Mutual Fund Association of Pakistan. Those funds are selected that have been in the market for at-least 5 years or those that have available daily returns for the same period. Standard deviation is used to measure the portfolio risk and the consistency of returns but since it is an absolute measure of risk we also use the coefficient of variation (CoV) ratio to calculate the relative measure of variability. Performance is measured by the common performance yardsticks; the Sharpe and Treynor ratios. This study found that conventional funds perform better in terms of average returns to investors than Islamic equity funds. However, both funds performed better than the market benchmark. The difference in key performance ratios of both funds was minimal suggesting the fact that Islamic mutual funds offer excellent growth potential in general and Islamic equity funds in particular.
Adaptive Commanding of Control Moment Gyroscopes with Backlash

Bourke, Justin G. MSAE, Embry-Riddle Aeronautical University, May 2019. Adaptive Commanding of Control Moment Gyroscopes With Backlash. The existence of backlash in mechanical systems provides significant challenges when attempting to control these systems to a high degree of precision. The imperfect meshing of gear or belt teeth deteriorates the performance of position controllers and tracking of small commands, producing unacceptable steady-state offsets, increased rise and settling times. Agile spacecraft often use control moment gyroscopes (CMGs) equipped with gear trains to efficiently provide torque for the fine attitude adjustments used in docking and precision stabilization maneuvers. A theoretical examination and a practical model is developed to study the effectiveness of both proportional-integral (PI) and model referencing adaptive controllers (MRAC) in overcoming the non-linearity introduced by gear lash. A Lyapunov analysis of the system’s equations of motion provides knowledge of its convergence, the tracking of ideal trajectories, and the rejections of disturbances. The objective is to create an adaptive control law that rejects the non-linearity and maintains acceptable performance with small torque commands. This control law is then validated in Simulink using a discontinuous backlash model.
Implementation of a novel P & O MPPT Controller for Photovoltaic System at Standard Test Conditions

This paper gives an ample idea of a novel P&O MPPT controller implementation to a DC-DC boost converter for a photovoltaic system at standard test conditions (STC) to track Maximum Power Point (MPP). The novel P&O MPPT controller implementation accompanies that initialization of duty cycle and calculation of power at the starting of the algorithm. Photovoltaic (PV) model is designed for lighting applications with a single diode. The PV system output is connected to a DC-DC boost converter to regulate the voltage up to a desired level. The novel P&O MPPT algorithm is implemented in a feed forward manner. The steady state condition reached at less than 0.05sec time, and tracks 10% more power at STC. The novel P&O MPPT controller results are compared with conventional P&O MPPT controller; the models are simulated in MATLAB/SIMULINK.
The Effects of Supply Chain Management on Project Manager's Capability and Sustainable Benefit Sharing in Global Leading Companies

This study was conducted to evaluate the effects of SCM on PM's capabilities and sustainable benefit sharing in leading global companies. To achieve this, statistical analyses were carried out through an empirical questionnaire survey of 426 PMs in SCM companies. The results showed that SCM commitment, vision and goal sharing have positive effects on PM's capabilities in leading global companies, boosting PM capability. Moreover, sustainable benefit sharing was improved along with SCM trust building, vision and goal sharing in global leading companies, supporting the usefulness of these variables. In contrast, SCM information sharing and trust building did not lead to significant acceleration of PM's capabilities, rejecting these variables. These findings indicate that SCM information sharing or trust building does not really help simple members to accelerate PM's capabilities. 요 약 본 연구는 글로벌 리딩 기업의 공급사슬관리(SCM)가 프로젝트 관리자(PM)의 역량과 지속가능 성과공유에 미치는 영향력을 밝히는데 목적을 갖는다. 연구방법은 설문지에 의한 실증조사방법으로 조사 후 통계분석 방법을 통해 수행하였다. 연구대상은 SCM 기업의 PM 426명을 대상으로 하였다. 연구결과는 글로벌 리딩 기업에서의 SCM의 몰입과 비전 및 목표공 유가 높을수록 PM의 역량에 긍정적인 영향을 미쳐 PM역량이 촉진되는 것으로 나타났다. 또한, 신뢰구축과 비전 및 목표공 유가 높을수록 지속가능성과 성과공유가 높아지는 것으로 나타났으며, 이들 변수의 유용성을 지지해 주었다. 반면 정보공유 와 신뢰구축은 PM의 역량을 높이는데 유의하지 않은 것으로 나타내 기각되었다. 이는 SCM에서 단순구성원의 정보공유나 신뢰구축만으로는 PM의 역량을 높이는데 큰 도움이 되지 않음을 의미한다. 즉, 글로벌 리딩 기업에서의 SCM은 몰입과 비전 및 목표공유가 높을수록 PM의 역량에 긍정적인 영향을 미쳐 PM역량이 촉진되고 또한, 신뢰구축과 비전 및 목표공유가 높을 수록 지속가능성과 성과공유가 높아지는 것으로 나타나 이들 변수의 유용성을 지지해 주었다. 반면 정보공유와 신뢰구축은 PM의 역량을 높이는데 유의하지 않은 것으로 나타나 기각돼 이는, SCM에서 단순구성원의 정보공유나 신뢰구축만으로는 PM의 역량을 높이는데 큰 도움이 되지 않음을 의미한다.
The Investment Performance of MESDAQ Market Initial Public Offerings (IPOs)

This study provides evidence on both the short-run and long-run investment performance of Malaysian initial public offering (IPO) companies that are listed on the MESDAQ Market. The factors that influence the performance are also investigated. In line with past Malaysian studies, the results of the raw and market-adjusted initial returns show that IPO companies are significantly underpriced in the short-run. However, in the long-run, both the CAR and the BHAR methods reveal that these companies underperform the market. Our results concerning the long-run performance contrast with the results observed by previous Malaysian studies using a sample of companies listed on the Main Board and/or the Second Board. However, they are consistent with the results reported in other countries. We find that companies in the technology sector, issued in a hot issue period and underpriced IPO, perform less well in the long-run, which supports the fad hypothesis of long-run underperformance. Our results suggest that investors who purchase IPO shares on the MESDAQ Market gain high positive returns in the short-run but do not fare well in the long-run. This study provides new information to investors when choosing IPOs listed on Bursa Malaysia. Classification-JEL:
Theoretical efficiency limits for thermoradiative energy conversion

A new method to produce electricity from heat called thermoradiative energy conversion is analyzed. The method is based on sustaining a difference in the chemical potential for electron populations above and below an energy gap and let this difference drive a current through an electric circuit. The difference in chemical potential originates from an imbalance in the excitation and de-excitation of electrons across the energy gap. The method has similarities to thermophotovoltaics and conventional photovoltaics. While photovoltaic cells absorb thermal radiation from a body with higher temperature than the cell itself, thermoradiative cells are hot during operation and emit a net outflow of photons to colder surroundings. A thermoradiative cell with an energy gap of 0.25 eV at a temperature of 500 K in surroundings at 300 K is found to have a theoretical efficiency limit of 33.2%. For a high-temperature thermoradiative cell with an energy gap of 0.4 eV, a theoretical efficiency close to 50% is found while the cell produces 1000 W/m2 has a temperature of 1000 K and is placed in surroundings with a temperature of 300 K. Some aspects related to the practical implementation of the concept are discussed and some challenges are addressed. It is, for example, obvious that there is an upper boundary for the temperature under which solid state devices can work properly over time. No conclusions are drawn with regard to such practical boundaries, because the work is aimed at establishing upper limits for ideal thermoradiative devices.

SOME PROPERTIES OF THE PRODUCT OF (P,Q) – FIBONACCI AND (P,Q) - LUCAS NUMBER

ABSTRACT: Some mathematicians study the basic concept of the generalized Fibonacci sequence and Lucas sequence which are the (p,q) – Fibonacci sequence and the (p,q) – Lucas sequence. For example, Singh, Sisodiya and Ahmad studied the product of the k-Fibonacci and k-Lucas numbers. Moreover, Suvarnamani and Tatong showed some results of the (p, q) Fibonacci number. They found some properties of the (p,q) – Fibonacci number and the (p,q) – Lucas number. There are a lot of open problem about them. Moreover, the example for the application of the Fibonacci number to the generalized function was showed by Djordjevicand Srivastava. In this paper, we consider the (p,q) – Fibonacci sequence and the (p,q) – Lucas sequence. We used the Binet’s formulas to show that some properties of the product of the (p,q) – Fibonacci number and the (p,q) – Lucas number. We get some generalized properties on the product of the (p,q) – Fibonacci number and the (p,q) – Lucas number.
Heliospheric modulation of cosmic rays: Monthly reconstruction for 1951–2004

[1] The differential energy spectrum of galactic cosmic rays in the vicinity of the Earth can be parameterized by the so-called force field model which has only one parameter, the modulation potential ϕ, for a given local interstellar spectrum. Here we present the series of monthly values of the modulation potential ϕ since February 1951, reconstructed using the data from the worldwide neutron monitor network and calibrated with precise balloon and space-borne direct measurements of cosmic ray energy spectrum. This work provides a long series of a parameter allowing for a quantitative estimate of the average monthly differential energy spectrum of cosmic rays near the Earth. A comparison with other occasional direct measurements of cosmic ray spectra confirms the reliability of the present reconstruction. The results can be applied in studies of long-term solar-terrestrial relations and the global evolution of the heliosphere.
POLLINATOR PERFORMANCE OF VISITORS TO THE SELF-INCOMPATIBLE CROP-PLANT B RASSICA RAPA BY SINGLE VISIT DEPOSITION AND POLLEN GERMINATION : A COMPARISON OF METHODS

Estimating the pollen-deposition effectiveness of flower visitors is fundamental to understanding their performance as pollinators. While estimates of visitation rates, pollen loads, and single visit deposition (SVD) are all useful proxies for performance, and so help to reveal the relative effectiveness of different visitors, none take into account the breeding system of the plants, or the quality of pollen deposited. Here we compare the performance of visitors to the self-incompatible plant Brassica rapa (turnip) using SVD and pollen germination. We also report the first use of the staining of Brassica rapa stigma papilla cells (known to reveal a specific reaction to self-pollen) to compare self-pollen deposition between insect visitors. We found that most of the pollen grains deposited by insect visitors (and therefore counted by SVD methods) were non-germinating self-pollen. A smaller proportion of grains were outcrossed and so germinated. There was also a significant positive relationship between environmental conditions (wind speed) and pollen deposition, but not pollen germination. Both methods identified Bombus spp. as the best-performing visitors on turnip flowers, followed by Eristalis spp. , whereas performance estimates for Episyrphus balteatus and ‘other hoverflies’ were no higher than controls for both methods. This study provides further insight into the methodology for estimating pollinator performance, especially in plants when only cross-pollen can germinate.
TS-RF: Combinatorial Optimization based Feature Selection Method for Network Intrusion Detection

Advancements in computer networks and communication technologies like software defined networks (SDN), Internet of things (IoT), microservices architecture, cloud computing and network function virtualization (NFV) have opened new fronts and challenges for security experts to combat against modern cyberattacks. Relying on perimeter defense and signature-based network security solutions like Intrusion Detection and Prevention Systems (IDS/IPS) have failed to deliver adequate level of security against new attack vectors such as advance persistent threats, zero days, ransomware, botnets and other forms of targeted attacks. Recent developments in machine learning and cognitive computing have shown great potential to detect unknown and new intrusion events where legacy misuse and anomaly based intrusion detection systems usually fail. In this research study we applied state of the art machine learning algorithms on UNSW-NB15 dataset for potential applicability to detect new attacks. We also proposed a novel wrapper based feature selection technique TS-RF using metaheuristic Tabu Search (TS) algorithm and Random Forest (RF) ensemble classifier. Results obtained by applying proposed feature selection technique i.e. TS-RF on UNSW-NB15 dataset show improvement in overall intrusion detection accuracy while it reduces computation complexity as it removes more than 60% features.
EXPERIMENTAL AND ANALYTICAL INVESTIGATION ON FAILURE BEHAVIOR OF STEEL PLATE – HPFRC COMPOSITE BEAMS

In this study, direct shear tests of HPFRC steel plate composite elements are conducted so as to evaluate shear stress – relative displacement curves of the interfaces. Besides threepoint loading experiments of the HPFRC steel plate composite beams were conducted. In those experiments, kinds of resigns and shear keys and its combinations applied in the interface are chosen as parameters. In this paper, how the interface affects the mechanical behaviour of the composite elements and beams is discussed. Furthermore, Finite Element Analyses, in which the shear stress – relative displacement curves found in the direct shear tests were installed, are performed to examine the failure mechanism of the composite beams. The paper describes that the ultimate load of the HPFRC and the steel plate composite beams is determined by interface failure and the FE analysis can predict the behaviour reasonably. Résumé Dans cette étude des essais de cisaillement direct de dalles composites BFUP / tôle en acier sont réalisés afin de déterminer les contraintes de cisaillement et les déplacements relatifs à l’interface acier BFUP. Par ailleurs, des essais de flexion trois points de barreau composite BFUP / plaque acier ont été réalisés. Dans ces essais, plusieurs sortes de résine de connexion et/ou de connecteurs sont testées. Cet article expose comment l'interface affecte le comportement mécanique des éléments composites. En outre, des analyses par éléments finis, dans lequel la loi de comportement contrainte de cisaillement / courbes de déplacement relatifs trouvés dans les essais de cisaillement direct sont effectuées afin d'examiner le mécanisme de rupture des éléments composite. L’article montre que la charge ultime de la dalle composite BFUP / acier est déterminée par la rupture de l'interface et que l'analyse par éléments finis fournit une prévision correcte du comportement de la structure.

Public transportation network design: a geospatial data-driven method

A R T I C L E I N F O A B S T R A C T Article history: Received: 10 June, 2017 Accepted: 17 July, 2017 Online: 01 August, 2017 The paper explores an issue of efficient public transportation network design as a part of the urban developing process. Having data about everyday residents travelling inside of an urban area, we can consider this data as people’s requirements for the public transport system. We propose a novel method for initial public transportation network design based on clustered geospatial data containing origin/destination point of travel patterns of residents. The core of a method is a set of four algorithms for selecting terminal clusters based on a number of centres (or focuses). The appropriate quality criteria are proposed: degree of transport demand satisfaction, the coefficient of non-straightness, and transport network density. Use cases allow evaluating a performance of proposed method and give sufficent conclusions about its application.
Study of the effect of additional background channels on the top Yukawa coupling measurement at a 1 . 4 TeV CLIC

The contribution of additional samples to the background expectation in a direct measurement of the top Yukawa coupling is investigated. In a previous study, the physics potential of a direct measurement of the top Yukawa coupling was investigated, using the process ee ! ttH at a p s = 1.4TeV Compact Linear Collider (CLIC) and reconstructed using the CLIC_SiD detector. The expected precision on the top Yukawa coupling was determined to be 4.27%, without beam polarisation. The inclusion of additional non-tt(+X) backgrounds has slightly increased the background expectation and an updated precision on the top Yukuwa coupling is determined to be 4.43% with no further optimisation of the selection.
ANALYTICAL EQUATION FOR MOTION CONSTRAINTS IN CONFINED ENVIRONMENTS FOR A P 6 R REDUNDANT ROBOT

Redundantrobots have additional mobilities that allows applications beyond the conventional robot. The additional mobilities of robots enable to include extras tasks, depending on the degree of redundancy. Several references present techniques and methodologies to solve the kinematic redundancy to robots with open or closed kinematics chains. In the cases of operation of robots in confined environments, the classical methods like Denavit-Hartenberg, for example, makes more difficult the precise analysis of the limits and constraints of robot’s joints movements. Recent works have shown that the use of screw theory, and its tools, turn the robots analysis easier, even for complex differential and kinematic model, when compared with the classical methods. The screw theory allows to introduce new solutions on study of singularity and motion constraint in confined environments. Again, researches have also shown ways to evaluate the movement constraints derived from a differential model of redundant robots, based on analytical expressions. These studies are limited to computational experiments in a planar redundant robot model. This paper presents theoretical aspects of the differential model and the mathematical strategies to obtain the expression of the constrained movement for aP6R redundant robot operating in confined environments including the avoiding collision as a secondary task. It is presented theoretical issues and the development of the position and differential kinematics model, based on screw theory. As result, it is explored the mathematical model to identify the P6R singular postures including the influences of the collision avoidance task
383 Assimilation and Modelling of the Hydrological Cycle : ECMWF ’ s Status and Plans

Several new types of satellite instrument will provide a rich source of additional humidity information in the next few years. The assimilation of cloud and rain observations from existing types of instruments will also provide important new humidity information. In an effort to make the best possible use of these data a re-formulation of the 4D-Var humidity analysis has been developed. The new formulation will better account for the wide variations in humidity in the vertical and at small scales in the horizontal, thus improving the interpretation and the spatial interpolation of humidity information from space and ground based observing systems. The theoretical basis for the new formulation, its practical implementation within the ECMWF assimilation system, and several illustrations of its performance, are presented. The status of the preparations for cloud and rain assimilation is given, including the development of linearized moist physics, the development of fast radiative transfer codes and the recent experimental results using rainfall rates from space borne microwave radiometers. Results of model validations (against in-situ data) of boundary-layer moisture are presented, indicating generally good agreement — often to within the absolute calibration accuracy of the measurements. We also present evidence of shortcomings in ECMWF’s current humidity analysis, from the operational data assimilation and forecasting system, and from the 40-year reanalysis project (ERA-40). Examples are shown of biases in the data and in the model that lead to biased humidity analyses. Although these biases are relatively small, they contribute to an over-prediction of precipitation in short-range forecasts and a marked spin-down in tropical rainfall.
IZA Discussion Paper No. 780

Temporary Contracts and Employee Effort Temporary contracts provide employers with a tool to screen potential new employees and have been shown to provide "stepping stones" into permanent employment for workers. For both reasons workers on temporary contracts have an incentive to provide more effort than permanent employees. Using indicators for unpaid overtime work and absences taken from the Swiss Labor Force Survey we present evidence that temporary workers indeed provide higher effort than permanent employees: Their probability of working unpaid overtime exceeds that of permanently employed workers by 60 percent. We show the heterogeneity of this effect across different types of temporary contracts, investigate differences between men and women, and discuss the relevance of adverse selection into temporary employment.
