An Empirical Analysis of Higher Moment Capital Asset Pricing Model for Karachi Stock Exchange (KSE)

The purpose behind this study is to explore the relationship between expected return and risk of portfolios. It is observed that standard CAPM is inappropriate, so we introduce higher moment in model. For this purpose, the study takes data of 60 listed companies of Karachi Stock Exchange 100 index. The data are inspected for the period of 1st January 2007 to 31st December 2013. From the empirical analysis, it is observed that the intercept term and higher moments coefficients (skewness and kurtosis) are highly significant and different from zero. When higher moment is introduced in the model, the adjusted R square is increased. The higher moment CAPM performs cooperatively perform well.
Method-Specific Access Control in Java via Proxy Objects using Annotations

Partially restricting access to objects enables system designers to finely control the security of their systems. We propose a novel approach that allows granting partial access at method granularity on arbitrary objects to remote clients, using proxy objects. Our initial approach considers methods to be either safe (may be invoked by anyone) or unsafe (may be invoked only by trusted users). We next generalize this approach by supporting Role-Based Access Control (RBAC) for methods in objects. In our approach, a policy implementer annotates methods, interfaces, and classes with roles. Our system automatically creates proxy objects for each role, which contain only methods to which that role is authorized. This thesis explains the method annotation process, the semantics of annotations, how we derive proxy objects based on annotations, and how clients invoke methods via proxy objects. We present the advantages to our approach, and distinguish it from existing approaches to method-granularity access control. We provide detailed semantics of our system, in First Order Logic, to describe its operation. We have implemented our system in the Java programming language and evaluated its performance and usability. Proxy objects have minimal overhead: creation of a proxy object takes an order of magnitude less time than retrieving a reference to a remote object. Deriving the interface—a one-time cost—is on the same order as retrieval. We present empirical evidence of the effectiveness of our approach by discussing its application to software projects that range from thousands to hundreds of thousands of lines of code; even large software projects can be annotated in less than a day.
The Origin of Molecular Clouds in Central Galaxies

We present an analysis of 55 central galaxies in clusters and groups with molecular gas masses and star formation rates lying between 10 8 and 10 11 M ⊙ and 0.5 and 270 M ⊙ yr − 1 , respectively. Molecular gas mass is correlated with star formation rate, Hα line luminosity, and central atmospheric gas density. Molecular gas is detected only when the central cooling time or entropy index of the hot atmosphere falls below ∼1 Gyr or ∼35 keV cm2, respectively, at a (resolved) radius of 10 kpc. These correlations indicate that the molecular gas condensed from hot atmospheres surrounding the central galaxies. We explore the origins of thermally unstable cooling by evaluating whether molecular gas becomes prevalent when the minimum of the cooling to free-fall time ratio ( t cool / t ff ) falls below ∼10. We find that (1) molecular gas-rich systems instead lie between 10 < min ( t cool / t ff ) < 25 , where t cool / t ff = 25 corresponds approximately to cooling time and entropy thresholds of 1 Gyr and 35 keV cm 2 , respectively; (2) min ( t cool / t ff ) is uncorrelated with molecular gas mass and jet power; and (3) the narrow range 10 < min ( t cool / t ff ) < 25 can be explained by an observational selection effect, although a real physical effect cannot be excluded. These results and the absence of isentropic cores in cluster atmospheres are in tension with models that assume thermal instability ensues from linear density perturbations in hot atmospheres when t cool / t ff ≲ 10 . Some of the molecular gas may instead have condensed from atmospheric gas lifted outward by buoyantly rising X-ray bubbles or by dynamically induced uplift (e.g., mergers, sloshing).
Traumatic Posterior Hip Dislocation in a 5-Year-Old: A Case Report and Review of the Literature

Traumatic hip dislocations in children are uncommon, yet constitute an orthopaedic emergency. Furthermore, the insignificant mechanism of injury oftentimes leads to a potential miss or delay in diagnosis. The nature of the injury may seem minor so as to not pursue further workup. For this reason it is imperative to have a high index of suspicion, as clinical assessment and judicious imaging are key to obtaining the patient’s correct diagnosis. Although there are various complications that may result from such an injury, the most commonly encountered and most catastrophic is Avascular Necrosis (AVN), of the femoral head; early concentric reduction is crucial in minimizing this risk and optimizing patient outcomes.
Jurnal Teknologi Optimization of Water Permeability of “ Green ” Non-Woven Filter Media from Lignocellulosic Fibers Using Taguchi Method

Water permeability is often used in characterization of the filter media. This paper focuses on the evaluating the effects of the process parameters and design parameters on the permeability of filter media as an output and considered as a response and the prediction of the optimal combination of synthesis parameters with an objective of maximizing the permeability. For this purpose, the Taguchi experimental design technique, analysis of varians (ANOVA), and signal-to noise (S/N) ratio were used. In this study, only eight filter configurations of Taguchi’s L8 orthogonal design were fabricated and tested. As a result from these experiments, the filter configuration satisfying the maximum water permeability value was determined, which show that statistical analysis is a useful method to quantify filter permeability objectively.
q-Ehrhart polynomials of Gorenstein polytopes, Bernoulli umbra and related Dirichlet series

This article considers some q-analogues of classical results concerning the Ehrhart polynomials of Gorenstein polytopes, namely properties of their q-Ehrhart polynomial with respect to a good linear form. Another theme is a specific linear form {\Psi} (involving Carlitz' q-analogues of Bernoulli numbers) on the space of polynomials, for which one shows interesting behaviour on these q-Ehrhart polynomials. A third point is devoted to some related zeta-like functions associated with polynomials
Vehicle steering wheel angle identification research based on dynamic program method

In order to improve the safety of vehicle manipulation as well as to provide a theoretical basis for the study of vehicle steering system and intelligent parking systems, a new method of vehicle steering wheel angle identification is presented – the dynamic program method. First, three freedom degrees of vehicle model is established. Then Bellman’s principle of optimality is used for minimizing the objective function. The dynamic optimization model of the load identification that the yawing angular velocity, lateral acceleration and vehicle body roll angle identified the steering wheel angle and angle velocity. The result shows that the dynamic program method for the steering wheel angle identification problem containing the measurement noise has strong adaptability, high accuracy and good anti-jamming capability.
Comparison of speech parameterization techniques for Slovenian language

The goal of speech parameterization is to extract the relevant information about what is being spoken from the audio signal. In modern speech recognition systems mel- frequency cepstral coefficients (MFCC) or perceptual linear prediction coefficients (PLP) are the two main techniques used. MFCC method is known to give better results when audio recordings are of high quality (no background noise, quality microphone) whereas the PLP performs better when the quality of audio is poor. In an attempt to close the gap between the two methods some modifications to the original PLP method are presented. They are mainly based on using a modified mel- filter bank with a number of filters resembling the number of spectral coefficients. In our work the effectiveness of proposed changes to PLP (RPLP features) were tested and compared against the MFCC and original PLP acoustic features. A number of 3-state HMM acoustic models were build using different acoustic feature setups (different filter banks, different number of filters) in order to assess which parameterization technique gives superior recognition accuracy. To achieve a more robust estimate of the recognition results when using various parameterizations three databases of different audio quality were used.
WASP-26b: a 1-Jupiter-mass planet around an early-G-type star

We report the discovery of WASP-26b, a moderately over-sized Jupiter-mass exoplanet transiting its 11.3-mag early-G-type host star (1SWASP J001824.70-151602.3; TYC 5839-876-1) every 2.7566 days. A simultaneous fit to transit photometry and radial-velocity measurements yields a planetary mass of 1.02 ± 0.03 MJup and radius of 1.32 ± 0.08 RJup. The host star, WASP-26, has a mass of
Informality and Poverty : Are these Processes Dynamically Interrelated ? The case of Argentina

Poverty and informal employment are often regarded as correlated phenomena. Many empirical studies have shown that informal employment has a causal impact on household poverty, mainly through low wages. Yet other studies focus on the reverse causality from poverty to informality, arising from a range of constraints that poverty poses to job holders. Only recently have empirical researchers tried to study the simultaneous two-way relationship between poverty and informality. However, existing studies have relied upon cross sectional data and static econometric models. This paper takes the next step and studies the dynamics of poverty and informality using longitudinal data. Our empirical analysis is based on a bivariate dynamic random effect probit model and recent panel data from Argentina. The results show that both poverty and informal employment are highly persistent processes at the individual level. Moreover, positive spillover effects are found from past poverty on current informal employment and from past informality to current poverty status, corroborating the view that the two processes are also shaped by interrelated dynamics.
Homology modeling of structure of NH2-terminal module of mammalian (Bos taurus) tyrosyl-tRNA synthetase

Mammalian tyrosyl-tRNA synthetase (TyrRS) is composed of two structural modules: the NH2-terminal catalytic core and cytokine-like COOH-terminal module. In order to elucidate the structural bases for the N-module functions we have used the computational prediction of its three-dimensional (3D) structure by comparative modeling approach, A model of the bovine TyrRS N-module represents the Rossmann nucleotide-binding fold (RF) which is linked to the α-helical domain (aHD). The RF domain forms a single β-sheet containing δ parallel and one attached antiparallel β-strands surrounded by a-helices. The connective polypeptide, CPl, inserted between β3and β4-strands of the RF domain is perturbed from the domain core. Comparative analysis of the multiple sequence alignment of known TyrRSs and the obtained model structure reveals the conservative surface elements, which could potentially form the tRNAbinding surface. This putative surface includes some exposed amino acid residues of CPI, e. g. essential LysJ46 and Lysl47 residues, which were identified earlier by site-directed mutagenesis.
Degradation Rates for Petroleum Hydrocarbons Undergoing Bioventing at the Meso-Scale

ABSTRACT Bioventing can be effective for the remediation of soil contaminated with petroleum hydrocarbons. However, implementing laboratory results in field scenarios is difficult due to the lack of scale-up factors. Accordingly, laboratory bioventing experiments were undertaken at the meso-scale and then compared with previously completed micro-scale tests to evaluate the important scale-up factor. The developed meso-scale system holds 4 kg of soil, with bioventing conditions controlled from a nutrient, airflow, and water content perspective. Three soils were tested, and categorized as loamy sand, silt loam, and a mixture. Results over a 30-day period showed a two-stage degradation pattern that encompassed first-order degradation rates as compared with the single-stage first-order degradation rate determined in the micro-scale study. For the first stage (0–8 days), the degradation rate for loamy soil was 0.598 day−1, with the silty soil at 0.460 day−1, and mixed soil at 0.477 day−1. After 8 days, the degradation rate constant for the loamy soil dropped to 0.123 day−1, with the silty soil dropping to 0.075 day−1, and the degradation rate for the mixed soil dropping to 0.093 day−1. Comparison of the measured degradation rate values with the results from the micro-scale experiments gave scale-up factors varying from 1.9 to 2.7 for the types of soil considered in the current study. These differences in degradation rates between the two scales show the importance of scale-up factors when transferring feasibility study results to the field.
Kinematics of the Isfjorden-Ymerbukta Fault Zone: A dextral oblique-thrust ramp in the Tertiary fold-thrust belt of Spitsbergen

The NNE-trending Isfjorden-Ymerbukta Fault Zone is an oblique structural element within the NNW-trending Tertiary transpressional fold-thrust belt of Spitsbergen, Arctic Norway. It can be traced for nearly 50 km, and separates two different structural domains in the fold-thrust welt of Oscar II Land, Central Spitsbergen. The fault zone is more than 500 m wide and contains several segments of highly folded/rotated, faulted and cleaved Triassic through Paleocene rocks. Displacement across the fault zone can be decomposed into (i) a reverse, top-to-the-ENE component with a minimum 650 m vertical throw, and (ii) a horizontal dextral component of approximately 5-10 km. Displacement across the fault decreases northward along strike, where the fault zone merges into parallelism with a ramp-system of the fold-thrust belt. Inherited, underlying Devonian(? )-Carboniferous structures may have controlled the location of the fault zone. Detailed studies of map and mesoscale faults and folds reveal complex geometries an.
HIGH-ENERGY ELECTROMAGNETIC OFFLINE FOLLOW-UP OF LIGO-VIRGO GRAVITATIONAL-WAVE BINARY COALESCENCE CANDIDATE EVENTS

We present two different search methods for electromagnetic counterparts to gravitational-wave (GW) events from ground-based detectors using archival NASA high-energy data from the Fermi Gamma-ray Burst Monitor (GBM) and RXTE All-sky Monitor (ASM) instruments. To demonstrate the methods, we use a limited number of representative GW background noise events produced by a search for binary neutron star coalescence over the last two months of the LIGO-Virgo S6/VSR3 joint science run. Time and sky location provided by the GW data trigger a targeted search in the high-energy photon data. We use two custom pipelines: one to search for prompt gamma-ray counterparts in GBM, and the other to search for a variety of X-ray afterglow model signals in ASM. We measure the efficiency of the joint pipelines to weak gamma-ray burst counterparts, and a family of model X-ray afterglows. By requiring a detectable signal in either electromagnetic instrument coincident with a GW event, we are able to reject a large majority of GW candidates. This reduces the signal-to-noise ratio of the loudest surviving GW background event by around 15–20%.
Economies of scale and scope in mental health care

Economies of scale and scope are usually derived under the assumption that the set of production possibilities are shared by all firms in an industry irrespective of whether they specialize in a single output or not. Mental health care institutions in the Netherlands vary substantially in the scale and the number of outputs. Estimation of one cost function therefore seems very restrictive and requires the allowance of zero-values. We used a translog cost function model with dummy-variables for different types of institutions, to allow for different technologies. We found evidence for differences in technologies between institutions specialized in counseling and integrated institutions that also performed other activities, expressed by the number of days in the hospital or permanent care, number of treatments in daycare or number of day activities. The marginal costs of counseling were lower for the integrated institutions than for the specialized institutions.
Effect of Poly Ethylene Glycol on CuO Nanoparticles and its Antibacterial Application

Pure CuO nanoparticles and chemically-precipitated Poly Ethylene Glycol (PEG) used as a capping agent CuO nanocrystal continuum (0.1, 0.2, 0.3, 0.4, 0.5 gm) was anatomized for structural and morphological research using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and Field - Emission Scanning Electron Microscopy (FE-SEM). Their X-ray Diffraction (XRD) analysis manifested monoclinic crystallinity in pure and PEG-capped CuO nanorods, with an average crystallite size of 21.63nm and 13-16nm respectively. The morphological analysis revealed their structural conformation. The FT-IR spectrum affirmed the presence of Cu-O bonds. The optical property of the aforesaid nanorods was studied by UV-Visible reflectance (UV-Vis DRS). The UV analysis showed that all the capped products show signs of good optical quality in the UV region and also the absorption edge was blue shifted with a band gap of 1.85 eV for 0.4gm PEG capped as results of quantum confinement effect. The antibacterial properties of the as-prepared nanostructures investigated for various human pathogens using disc diffusion method. The result showed the significant antibacterial activity both gram positive and gram negative bacteria.
Properties of Discrete Framelet Transforms

As one of the major directions in applied and computational harmonic analysis, the classical theory of wavelets and framelets has been extensively investigated in the function setting, in particular, in the function space L2(R ). A discrete wavelet transform is often regarded as a byproduct in wavelet analysis by decomposing and reconstructing functions in L2(R ) via nested subspaces of L2(R ) in a multiresolution analysis. However, since the input/output data and all filters in a discrete wavelet transform are of discrete nature, to understand better the performance of wavelets and framelets in applications, it is more natural and fundamental to directly study a discrete framelet/wavelet transform and its key properties. The main topic of this paper is to study various properties of a discrete framelet transform purely in the discrete/digital setting without involving the function space L2(R ). We shall develop a comprehensive theory of discrete framelets and wavelets using an algorithmic approach by directly studying a discrete framelet transform. The connections between our algorithmic approach and the classical theory of wavelets and framelets in the function setting will be addressed. Using tensor product of univariate complex-valued tight framelets, we shall also present an example of directional tight framelets in this paper.
Design and Development of a Software Module for Minimizing Transportation Cost

The goal of this project is to design and develop a software module to solve a transportation problem, relating to minimizing costs to transport finished goods from multiple origins to multiple destinations. The transportation problem will be modeled as a linear programming model, using AMPL linear programming (LP) software. A graphical user interface (GUI) will be developed to enable the user to enter the data and parameters for the transportation problem. The GUI will be developed using C# programming language within the Microsoft . NET framework. The GUI will also enable the user to launch the AMPL module to solve the transportation problem to calculate optimum transportation costs. A relational database will be designed and developed to store the parameters and data for the AMPL LP module. Both the AMPL LP model and the GUI will be interfaced with the relational database.

An investigation into the geometric parameters affecting field uniformity in four pole magnetisers

In recent years, the field-metric method for measuring the joule losses set up in an electrical steel laminate when subjected to a rotating field has gained popularity. The ideal geometry of the magnetiser required to set up such a field is still however the subject of much debate. The work presented in this paper aims at providing some useful guidelines which might be considered when undertaking the construction of the simplest of such magnetizing setups having four salient poles excited by a two phase system and using a square sample. A 3D model for this rotational power loss tester was simulated for different pole geometries with the induction uniformity being assessed for every alteration.
Linking Farm and Market Models to Analyse the Effects of the EU Nitrate Directive for the Dutch Agricultural Sector

This paper presents a modeling system that can be used to analyze the trade off between economy and environment. It takes into account manure policy, farm structure and manure surpluses at farm level as well as the economic effects of manure surpluses at market level. The modeling system consists of two models that are linked to each other by at the one-hand manure prices and distribution of manure over different destinations and at the other hand changes in agricultural and total manure production. One model is the so-called Manure and Ammonia Model (MAM). This model calculates manure surpluses and deficits at the farm level and distribution of manure to own farm, own region, other regions, export abroad and processing at the regional level. Moreover, MAM also calculates ammonia emissions coming from different sources. The second model is a market model that includes the most important agricultural markets. The models are calibrated for 2002. The modeling system is tested to analyze the effects of sharpened manure policies until 2006.
