Professional Portfolio Managers - a Setting for Momentum Strategies

Most real world market participants are professional portfolio managers (PPM), which means that they are not managing their own money, but rather managing money for other people (e.g. mutual funds, pension funds). This situation generates an agency feature which has relevant consequences, as investors lacking specialized knowledge may evaluate the PPM just based on his past performance (Performance Based Evaluation - PBE). The objective of this paper is to extend the analysis of the PPM's context inferring the effectiveness of feedback trading in this setting and so describing a source of market's inefficiency. In this sense, we propose a model which considers that professional investment is conducted by a relatively small number of highly specialized PPM using other people's capital. In a deductive way, we reach four propositions which justify the effectiveness of momentum strategies.
A Review : Security Threats and Defensive Strategis in WSN

Wireless Sensor Networks (WSNs) are formed by deploying as large number of sensor nodes in an area for the surveillance of generally remote locations. Wireless Sensor Networks consist of a large number of pocket-sized sensors deployed in autonomous manner in the area under surveillance. These sensor networks are used in sensitive, unattended and remote environment. WSNs suffer from many constraints, including low computation capability, small memory, limited energy resources, susceptibility to physical capture, and the use of insecure wireless communication channels. These constraints make security in WSNs a challenge. This paper studies the security problems of WSN based on its resource restricted design and deployment characteristics and the security requirements for designing a secure WSN. Also, this study documents the well-known attacks at the different layers of WSN and some counter measures against those attacks.
Tracheary elements characteristics of Kigelia africana (Lam) Benth and Newbouldia laevis (P. Beauv) Seemann ex. Bureau growing in rainforest and derived savanna regions of Edo State, Nigeria.

Vari ations in dimensions of tracheary elements of Kigelia africana (Lam) Benth. and Newbouldia laevis (P.Beauv.) Seemann ex Bureau growing in the rainforest and derived savanna areas of Edo State are reported. Both taxa exhibit short vessel lengths ( 3.0µm) and decrease in wall thickness from derived savanna to the rainforest area. Taxa vessels are tailless having simple perforation with simple pits arranged in rows. Fibres are long (1600 µm), medium (900-1600µm) except in K. africana growing in the derived savanna areas where short lengths (<900µm) were encountered. Variations in fibre dimensions were significant at 1% and 5% probability levels between K. africana growing in the two ecological zones but were only significant at 5% probability level in fibre diameter of N. laevis growing in the two ecological zones. Taxa fibres were non-pitted and septations were only encountered in species found in the rainforest zone. Fibre /vessel length ratio in both taxa is greater than 1 and ratios approaching 10 are phylogenetically more advanced and specialized. Higher mean maximum values were obtained in vessel element lengths of K. africana and N. laevis growing in the rain forest zone. N. laevis from the derived savanna had thicker fibre walls than its counterpart in rain forest. Both species are suitable for various end-uses but are however not suitable for high grade pulp because of their relative low fibre length and runkel ratio (<1) which was low. (Okoegwale.

Experimental evaluation of a safety aware impedance controller design

During this master project the proposed safety aware impedance controller of Tadele et al. (2014b) has been evaluated experimentally. This controller is designed to be used on the Phillips Robotic Arm (PRA) used during the BOBBIE project. Within in this project a controller is requested which is able to safely interact with its environment. To test the proposed controller, the robotic arm of the KUKA youBOT is used. This manipulator is also able to perform different tasks in multiple degrees of freedom, like the PRA, however, it is better suited as a test platform. Two different joints of the KUKA youBOT are used during the experiment to first obtain measurements in joint space by using the one degree of freedom implementation. After these measurement the controller is evaluated using the proposed controller in cartesian space. During the experiment it was noticed that the controller was suffering from the available friction in the joints, therefore a plant compensation controller is designed to compensate for this friction. The performed experiments have shown that the controller remains stable while the control parameters are changed to maintain the desired power and energy limits. By adding the plant compensation controller the friction was compensated however, this interferes with the passivity of the controlled system. Therefore it will be advised to partially compensate for friction such that no overcompensation occurs.
Identifying and ranking factors influencing job stress among Health, Safety and Environment (HSE) Employees in Phase 14 of South Pars: a cross sectional study in South of Iran

Introduction The present paper aims at identifying and ranking the factors affecting job stress of HSE employees in the phase 14 of the South Pars (a petroleum company in south of Iran). Methods In this cross sectional study, all HSE employees in one of the phases in south pars of Iran (the phase 14) including 150 employees were investigated in 2015. The data were collected using a questionnaire and measuring some environmental and occupational factors such as sound and chemical pollution. Results The validity of the questionnaire was approved by opinion of the 10 expert persons in this field (Content Validity Index .85%) and the reliability of the questionnaire was approved by Cronbach Alpha equal to 0.70. At present study the one sample T test indicated that the environmental and managerial factors affect job stress of the HSE employees. Among the environmental factors, long working hours, poisonous materials risks, air pollution, heat and moisture and air pollution mostly affect job stress, respectively. On the other hand among the managerial factors, job security, lack of meritocracy, not in time payment and prejudice in salary affect job stress the most, respectively. Conclusions As the results of this study, respect to environmental and occupational factors according to employees’ viewpoint in each industry is too important.
A Frobenius problem on the knot space.

According to J.-L. Brylinski, there is a natural almost complex structure J on the space K of all knots in the Euclidean space R3. The almost complex structure is formally integrable on K, i.e, the Nijenhuis tensor of J vanishes. The problem is whether J is integrable and hence K is a complex manifold. In this paper, we study the integrability of J explicitly in view point of a Probenius problem.
Journal of Rehabilitation in Civil Engineering

Article history: Received: 07 June 2017 Accepted: 05 September 2017 Nowadays, the better performance of lightweight structures during earthquake has resulted in using lightweight concrete more than ever. However, determining the compressive strength of concrete used in these structures during their service through a none-destructive test is a popular and useful method. One of the most original approach of nondestructive testing to obtain of compressive strength of concrete used in structures is ultrasonic pulse velocity test. The purpose of this research is predicting the compressive strength of LWA concrete by proposing an accurate mathematical formulation. Many samples of lightweight aggregate concrete, made by expanded clay, have been produced and tested. After determining the actual compressive strength and indirect ultrasonic pulse velocity for each sample, a relationship was derived to estimate the compressive strength through Gene Expression Programming (GEP). The results show the presented equation shows high accuracy in predicting the compressive strength of LWA and the estimated outcomes have a considerable compatibility with actual samples.
Parameters calibration for parallel differential evolution based on islands

We are studying different alternatives to obtain a version of the Differential Evolution (DE) algorithm that improves the solutions quality properties. One of the parallel alternatives, named Island Model, follows a Master/Worker scheme. With this model, multiple instances of DE are executed in parallel on various computing nodes or islands, each of them considering a different population of individuals. Each worker makes the search process, and communicates with each other to exchange information with certain frequency. This model significantly promote the exploration of a larger search space, which leads to good solutions quality. The aim of this paper is to analyse the behaviour of this model, when setting each island with different input parameters. We apply some input configuration tests for the islands, in order to analyse the impact in the solutions quality and the execution time, taking into account the crossover probability and mutation factor, and the crossing type. These parameters are crucial to guide the search towards certain areas of the search space.
Mechanics of monoclinal systems in the Colorado Plateau during the Laramide orogeny

Monoclines developed in the Colorado Plateau region during the Laramide orogeny are divided into westem and eastern groups by a broad NNW trending antiform through the central part of the plateau. In the western group the major monoclines verge to the east, whereas in the eastern group the major monoclines verge to the west. Paleogeographic reconstruction based on paleocurrent indicators and sedimentary facies distribution suggests that the broad antiform was developed uring the Laramide orogeny and was coeval with the formation of the monoclines in the plateau. This relationship implies that the monoclines were drag folds verging towards the center of the plateau as a response to the antiformal warping of the plateau. To simulate the warping of the plateau region and the stress distribution that produced the variable trends of the monoclines, an elastic thin plate model considering in-plane stress was developed. This model assumes that (1) sedimentation i the Laramide basins provided vertical loading along the edge of the plateau region, (2) frictional sliding was operating along the Laramide faults on the northern and eastem boundaries, and (3) the greatest regional compressive stress was oriented in the N60øE direction and was applied uniformly along the western and southwestram sides ,,•' tho platoa,, Buoyancy due to instantaneous i ostatic adjustment of crustal thickening or magmatic addition was also considered. The result of the model suggests that the frictional strength of the Uinta thrust system on the northern side of the plateau is at least 2 times greater than that along the Park Range and Sangre de Cristo thrust systems on the eastern side of the plateau in order to explain the observed monoclinal trends and the warping pattern within the plateau during the Laramide orogeny.
Factors Affecting Debt Recovery in Commercial Banks In Kenya a Case Study at Equity Bank Kenya Limited

The study was informed by the changing business environment in Kenya which had resulted many challenges in the banking industry. These challenges include worsening economic conditions, monetary policy changes, financial sector liberation and more importantly intense competition. Despite phenomenal growth, the Kenyan banking industry has experienced a myriad of challenges in regards to credit risk management. The research design used in the study was descriptive research design. The response rate was 75.6% and was deemed fit for the study. The data was subjected to various tests before the analysis to check whether it was normal so as to enable subsequent analyses. The data was found to be normal after the Shapiro Wilk the p-values for all the dependent variables (ratios) were less than 0.05 at 5% level of significance. Detrended Q-Q plots and the Box Plots established (confirmed) the same. For reliability, the questionnaire was found to a reliable tool for the study and it had the internal consistency required since it had Cronbach alpha value of 0.731> 0.7 All the values of the variables in the Correlation exhibit Pearson Correlation values below the 0.8 threshold. This shows that there is no multi-collinearity between the variables and thus the data was deemed fit to be subjected to further parametric tests. The findings were analyzed as per the research objectives. The relationship of reputational risk on debt was positive and insignificant with a p-value of 0.106 on the correlation matrix. The relationship between level of professional qualification and employee’s competency and debt recovery was positive and significant with a p-value of 0.000 on the correlation matrix. The relationship between collateral and debt recovery was positive and significant with a p-value of 0.002. The study concluded that there are various factors that affect debt recovery in Equity Bank which includes collateral, reputational risk and professional qualification and employee’s competency. The research also recommends studies to be done across the region and compare the findings. It would be interesting to find out how the results of the same study would be in other economies. The study was limited on Equity; this made the sample size to be very small.
Optimization of dental implant using genetic algorithm

The subject of the present work is optimization of the modern implant system Osteoplant, which was created and is still developed by Foundation of University of Medical Sciences in Poznan. Clinical observations point to the occurrence of both early and late complications in the case of all two-component implant systems. In many cases, these problems are caused by mechanical fractures of the implants themselves. The obtained results of the previous studies focused on necessary changes of the implant mechanical behavior, which helped to achieve the required long-term strength. However, modifications of the present dental implant system are not obvious. In this paper, an optimization of the Osteoplant dental implant system, with the use of FEA and genetic algorithms is discussed.
Future Developments in Clinical MEG and Its Combination with nTMS Mäkelä

Development of clinical MEG will provide biomarkers of neurodegenerative disorders by producing functional and effective connectivity measures within and between distinct functional brain areas. It is highly probable that neurodegenerative disorders damage these connections early in their course and detection of such changes will be feasible with sophisticated signal analysis of MEG data. Combining MEG and nTMS has already proven to be valuable in clinical evaluations. Such combinations will assist us in understanding the complex brain networks and the effective connectivity within them both in the healthy and diseased brains.
Power factor preregulators based on combined buck-flyback topologies

The limitation imposed on the achievable power level by the IEC 1000-3-2 standard in buck-derived power factor preregulators, is overcome by using a combined buck-flyback power stage. Two different step-down converters are proposed in this paper, which incorporate an auxiliary flyback stage. The auxiliary stage uses the same switch of the main converter, plus an additional power switch commutated at the line frequency. As compared to a simple buck rectifier, with this solution the harmonic content of the absorbed line current, at a given power level, can be reduced, thanks to the resulting increased conduction angle of the input rectifier bridge. Experimental results based on a 1 kW prototype are reported to validate the theoretical analysis of the proposed topologies.
Teacher ’ s Gender-Related Beliefs about Mathematics 1

Mathematics has been stereotyped as a male-dominated subject, and there is considerable evidence to support this belief. There has been much research in the past three decades on gender-related differences in elementary and secondary school mathematics. The research found that teachers possess different beliefs about male and female students that influence their teaching behaviour, which then directly or indirectly impact their students’ behaviours, beliefs, and achievements in mathematics. Based on data collected from teacher questionnaire surveys in the Chinese Mainland and Hong Kong, this study examines teachers’ beliefs about the achievements of boys and girls in mathematics. The study also compares the findings in the two regions surveyed. Results showed that teachers gave more attention to boys than girls, regardless of the teacher’s gender. Not only are teachers more likely to recall more boys than girls, but also more boys than girls with average academic standards.
Adsorption Studies of Heavy Metals on Tectona Grandis: Removal and Recovery of Zn (II) from Electroplating Wastes

Teak leaves (Tectona grandis), an inexpensive material has been utilized as an adsorbent for the removal of Zn (II) from aqueous solutions as well as from industrial waste. The effects of contact time, pH, concentration, temperature and adsorbent dosage on the removal of Zn (II) have been studied. The percent removal of different metals on teak leaves has been found in the order: Zn (II) > Cd (II) > Ni (II) > Cr (VI). Thermodynamic parameters like free energy, entropy and enthalpy changes for the adsorption of Zn (II) have been computed and discussed. The kinetics and the factor controlling the adsorption process have also been studied. The analytical application has been demonstrated by removing Zn (II) from electroplating waste water using batch as well as column operations. The recovery by column operation was found to be higher (96%) than that by batch process (76%).
Lawrence Berkeley National Laboratory Recent Work Title Longitudinal Evaluation of Myocardial Fatty Acid and Glucose Metabolism in Fasted and Nonfasted Spontaneously Hypertensive Rats Using MicroPET / CT Permalink

Using longitudinal micro positron emission tomography (microPET)/computed tomography (CT) studies, we quantified changes in myocardial metabolism and perfusion in spontaneously hypertensive rats (SHRs), a model of left ventricular hypertrophy (LVH). Fatty acid and glucose metabolism were quantified in the hearts of SHRs and Wistar-Kyoto (WKY) normotensive rats using longchain fatty acid analog F-fluoro-6-thia heptadecanoic acid (F-FTHA) and glucose analog F-fluorodeoxyglucose (F-FDG) under normal or fasting conditions. We also used F-fluorodihydrorotenol (F-FDHROL) to investigate perfusion in their hearts without fasting. Rats were imaged at 4 or 5 times over their life cycle. Compartment modeling was used to estimate the rate constants for the radiotracers. Blood samples were obtained and analyzed for glucose and free fatty acid concentrations. SHRs demonstrated no significant difference in F-FDHROL wash-in rate constant (P1⁄4 .1) and distribution volume (P1⁄4 .1), significantly higher F-FDG myocardial influx rate constant (P 1⁄4 4 10 ), and significantly lower F-FTHA myocardial influx rate constant (P1⁄4 .007) than WKYs during the 2009-2010 study without fasting. SHRs demonstrated a significantly higher F-FDHROL wash-in rate constant (P 1⁄4 5 10 ) and distribution volume (P 1⁄4 3 10 ), significantly higher F-FDG myocardial influx rate constant (P 1⁄4 3 10 ), and a higher trend of F-FTHA myocardial influx rate constant (not significant, P 1⁄4 .1) than WKYs during the 2011–2012 study with fasting. Changes in glucose plasma concentrations were generally negatively correlated with corresponding radiotracer influx rate constant changes. The study indicates a switch from preferred fatty acid metabolism to increased glucose metabolism with hypertrophy. Increased perfusion during the 2011-2012 study may be indicative of increased aerobic metabolism in the SHR model of LVH.
p73 Gene Overexpression Induces Apoptosis and Increases Chemosensitivity in Human Lung Adenocarcinoma Cells A549

Objective: As some NSCLC harbor wild-type p53, it would be important to override the resistance mechanism due to wild-type p53 in NSCLC gene therapy. The p53 family member p73 has significant homology to p53 tumor suppressor. The aim of this work was to observe the degree of apoptosis and chemosensitivity of p53-resistant human lung adenocarcinoma A549 cells following wild-type p73 gene transfer alone or combined with chemotherapetutic agents. Methods: The pcDNA3-HA-p53 or pcDNA3-HA-p73αplasmids were transferred into in vitro cultured human lung adenocarcinoma cell line A549 with Dosper. The cells resistant G418 were selected. The expressions of exogenous p53 or p73α gene were examined by Western blot. MTT assay were used to analyze the response of transfected cells to Cis-dichlorodiamine platinum(CDDP) or adriamycin(ADM). The drug-induced apoptosis of transfected cells was measured by flow cytometry assay, TUNEL technique and DNA fragmentation. The biological behavior change of cells was observed by colony formation assay. Results: The transfected lung adenocarcinoma cells A549 could overexpress P53 or P73αprotein stably. We found that p73, but not p53, is capable of sensitizing A549 cells to apoptosis induced by CDDP or ADM. Lower concentration of chemotherapeutic agents without inhibition essentially can suppress growth of p73 transfected cells markedly. p73 gene transfer combined with CDDP or ADM was shown to be even more effective in suppressing growth in A549 cell. Conclusions: Exogenous p73 gene was capable of enhancing the sensitivity of wild-type p53 human lung adenocarcionoma cells A549 to chemotherapeutic agents. It suggests the possibility of using p73 gene to improve p53-resistant tumor treatment. The combined treatment with p73 gene and chemotherapy could be an attractive strategy for inhibiting progression of NSCLC through effective induction of apoptosis.
