Classification of Android Malware Applications using Feature Selection and Classification Algorithms

Smartphones have become a potential part of our lives, and this led to a continued increase in the number of smartphone users. The growing number of users attracts hackers to develop malware applications to steal the private information and causing potential financial losses. Due to the fast modifications in the technologies used by malware developers, there is an urgent need for more advanced techniques for malware detection. In this paper, we propose an approach for Android malware classification based on features selection and classification algorithms. The proposed approach uses the permissions used in the Android app as features, to differentiate between the malware apps and goodware apps. The information gain algorithm is used to select the most significant permissions, then the classification algorithms NaivBayes, Random Forest and J48 used to classify the Android apps as goodware or malware apps. The experimental results show that random forest algorithm achieved the highest precision of 0.898 with a lowest false positive rate of 0.110.
Measurement of loss components in two induction machines and three types of frequency converters

This report presents the results obtained from measurements on two induction machines (IMs) fed by three different types of frequency converters; the focus has been on determining the different loss components of the drive system and how these varies with the frequency at different operating points. The mechanical power output was measured with a torque transducer and for determining the electric power a six-channel power analyzer was used. The main conclusion is that the method used gave good results; it managed to explain nearly all the losses in the induction machine. The part of the losses not accounted for was 13% in the worst case, which can represet the stray losses. Furthermore, it was established how the different loss components varied with frequency and load; it was found that the overall losses decreased with increasing frequency for all load situations An investigation of three field measurement methods was also preformed; the slip method, the current method and the air gap torque method were considered. The two first methods gave unsatisfying result. The air gap torque method gave a result very close to the measured output power. The estimated efficiency of the two methods varied with a maximum of 3.7% and this variation became less than 0.5% at loads above 0.5 p.u output power.
A Review of the Healthy Mindsets for Super Kids Program

The notion of resilience has emerged in the 21st century as an important factor influencing children's responses to adverse events. In the past 10 years, resilience theory and resilience programs for children have flourished globally. ‘Healthy Mindsets for Super Kids’ is a new program aimed at building resilience in children aged 9–14. The program features 10 modules, illustrated by superhero themes, on topics of communication and social skills, anger management, grief and loss, body image, healthy relationships, and positive thinking. This review will introduce the Healthy Mindsets for Super Kids program (Jessica Kingsley publishers, 2014) in use by practitioners in educational, community and mental health settings. It will describe its content, evaluation and the value in building resilience in children at risk of mental health issues.
The Effects of MIMICing

In this exploratory study, 135 pre-service teachers developed an instructional plan for a case study within the MIMIC (Multiple Intelligent Mentors Instructing Collaboratively) computer-based environment. Threedimensional, animated pedagogical computer agents, representing constructivist and instructivist approaches to instructional planning, served as instructional mentors within the environment and were available to provide suggestions. The research design was comprised of two two-factor MANOVAs with the instructivist agent (present, absent) and constructivist agent (present, absent) serving as the two factors, with two groups of dependent measures: awareness and attitude. Additionally, the value of the agents and overall differences between high and low performers were investigated. Regarding awareness, main effects for the presence of the constructivist agent indicated that when the constructivist agent was present, participants tended to report a change in their perspective of instructional planning, reflected less on their thinking, and developed instructional plans rated as more constructivist in underlying pedagogy. Regarding attitude, a main effect for the presence of the instructivist agent indicated that when the instructivist agent was present, participants reported a more negative disposition regarding instructional planning. Results are discussed in terms of the impact on teaching instructional planning to pre-service teachers. (Contains 35 references.)

A Review of the Transition to College Literature in Sociology

Background/Context This review focuses on the transition to college literature in sociology published since 1983 with an emphasis on revealing the contribution that sociology has made to our understanding of under-represented U.S. populations and their transition into and completion of postsecondary education. Purpose The review is organized around four main themes: 1) college preparation, 2) college access, 3) financing college, and 4) college completion and/or retention. Five dimensions that cut across these themes are emphasized: 1) disadvantaged or underrepresented students, 2) parents, families, and social networks of these students, 3) institutions, 4) federal, regional, state, local, or other policies, and 5) systemwide or interactive factors. Research Design This is an analytic essay of prior analyses. These prior analyses include but are not limited to a range of methods, such as qualitative case study and secondary analysis of national, regional, and institutional data. Findings/Results This review finds that while most sociological research has focused on college preparation, with disadvantaged students at the center of this work, very little research has studied college financing. Conclusions/Recommendations Sociological studies relevant to the transition to college continue to strive toward that end, but the field still remains underdeveloped with regard to an emphasis on how the wider societal system of stratification and opportunity interact with individuals, social groups, and educational institutions in a dynamic interplay that affects opportunities for quality educational advancement. In some respects, the prominence of the status attainment framework has limited progress in the field of sociology. Although multilevel modeling affords the opportunity to consider not just the individual, but the individual embedded in particular educational contexts and other contexts, the role of institutional and systemwide factors requires further development among sociologists of education.
Influence of rotating bending fatigue test on the mechanical parameters of standard specimens

The aim of this paper is determining the rate of fatigue damage due to applying rotating bending fatigue test on standard specimens. The influence of rotating bending fatigue tests are investigated on the mechanical parametersyield strength, ultimate strength, percentage of area reduction and the percentage of elongationon standard specimens. Different fatigue loads are applied to the specimens on which fatigue test was run in such a way that no specimen reached to its fracture cycle. Then, tensile test was done on the specimens and the mechanical parameters were determined for each specimen. Then, the data was compared with the data obtained from the specimen on which no fatigue test was run and the tensile test was carried out on it directly. Results show that, in comparison to the other mechanical parameters, ultimate strength is more sensitive to the fatigue test that can be a reliable criterion for fatigue damage.
2006-1213: QUANTITATIVE ANALYSIS OF PROGRAMS: COMPARING OPEN-SOURCE SOFTWARE WITH STUDENT PROJECTS

The lack of quantitative measures is a common problem in a programming course. Even though most students understand the importance of comments and good program structures, there is no quantitative “rule of thumb” to guide students in determining whether their programs have suﬃcient comments or are well-structured. For example, an instructor may require one line of comment for every ten lines of codes. These numbers are determined without suﬃcient scientiﬁc support; hence, students may resist the requirements and treat them as burdens. Open-source programs are widely used today and they can be considered as samples for teaching programming. We analyze 6 open-source software projects with 6233 ﬁles and 3.27 million lines of code to discover their commonalities. The projects are python, gdb, emacs, httpd, kde, and doxygen. These open-source programs are used and contributed by many programmers. These particular programs are selected as examples of high quality code by virtue of their extensive and successful use in industry and academia. These programs are used also because it is diﬃcult to obtain large-scale non-trivial programs from companies and sample programs from textbooks are usually very small. Because quality measures are often subjective, we focus on quantitative measures that can be objective and obtained by software tools.
Soluble triggering receptor expressed on myeloid cells-1 as a useful biomarker for diagnosing ventilator-associated pneumonia after congenital cardiac surgery in children

The present study aimed to assess the usefulness of soluble triggering receptor expressed on myeloid cells 1 (sTREM-1) in the diagnosis of ventilator-associated pneumonia (VAP) in paediatric patients with congenital heart disease (CHD) following cardiac surgery. The current prospective study enrolled 48 patients with congenital heart diseases who were suspected of having VAP; these patients were undergoing cardiac surgery between August 2016 and October 2017 in the Cardiac Intensive Care Unit of Shanghai Children's Medical Center (Shanghai, China). A total of 31 patients were diagnosed with VAP using a polymerase chain reaction (PCR) assay, while 17 patients without VAP were designated as the Non-VAP group. A bronchoscopy was performed and samples were collected for measurement on the day that VAP was diagnosed. The sTREM-1 levels were measured in bronchoalveolar lavage fluid (BALF) and exhaled ventilator condensate (EVC). BALF specimens were also sent to the microbiology laboratory for PCR assays and quantitative culturing. The positive detection rate of bacteria using the PCR assay and traditional culture was 64.6% (31/48) and 39.6% (19/48). sTREM-1 was significantly higher in the BALF (146.21 pg/ml vs. 118.06 pg/ml) and EVC (125.29 pg/ml vs. 120.48 pg/ml) of patients with VAP demonstrated compared with the patients without VAP. The findings suggest that the detection of sTREM-1 in BALF and EVC samples may be useful for the diagnosis of VAP following heart surgery in children.
Factors Influencing Work Efficiency in China

The preferred methods of conflict handling are largely sociologically prescribed in China, but those methods could reduce efficiency in the workplace. This study examined factors that could influence the efficiency of working people since efficiency is important to the successful operation of organizations. Some relatively unexplored personality variables, i.e., Creativity and Resilience, Esteem from Others, Attribution for Success (to Self), and Attribution for Success (to Others), and some more usual variables, i.e., Conscientiousness, Self-Confidence, and Organizational Socialization (Training, Understanding, Coworker Support, Future Prospects), were tested for their expected positive relationships to three dependent variables, i.e., Work Efficiency, Conflict Handling-Avoidance, and Conflict Handling-Compromising. Questionnaire data from 192 Chinese employees in Mainland China were analyzed to assess these relationships. Correlation results indicated that all variables (except Future Prospects and Attribution to Others) were positively related to Work Efficiency, and most were positively related to both Conflict Handling-Avoidance, and Conflict Handling-Compromising. Results for the relationships of the personality and social variables to conflict handling and work efficiency are discussed in terms of Chinese culture.

THREE-DIMENSIONAL RE-EVALUATION OF THE DEFORMATION REMOVAL TECHNIQUE BASED ON "JIGSAW PUZZLING"

Retrodeformation is the process of removing distortions in fossils caused by tectonic or overburden stresses. These methods are very important for paleontologists because they can be used to estimate true fossil shapes necessary for studies in systematics, phylogenetics, and functional morphology. Deformation may be brittle, breaking the specimen apart but leaving the original shape of the broken pieces unaltered, or plastic, altering the original shape without breakage. The effects of plastic deformation are often overlooked in fossils with extensive brittle deformation. Anthropological studies dealing with brittlely-deformed bones tend to rely on simple “jigsaw puzzle” reconstruction, in which fractured pieces are manually or digitally placed back together. These methods assume that most of the deformation is brittle, and that the original fossil shape can be restored without plastic retrodeformation. We tested the validity of jigsaw puzzle reconstruction by using three-dimensional (3-D) computational techniques. More specifically, we examined if plastically deformed skull pieces can be arranged to form a ‘symmetrical skull’ that morphologically differs from the true skull under a digitally controlled environment. A cranium of a Woolly Monkey (Lagothrix lagotricha) was digitized using a 3-D laser scanner. We virtually fragmented and then plastically deformed this skull to create skull pieces with known plastic deformation. We found that these pieces fit well onto the true skull and an incorrect skull shape equally well, suggesting that “jigsaw puzzle” methods can lead to inaccurate specimen reconstruction that superficially appears ‘correct’. We conclude the plastic deformation must be removed before “jigsaw puzzle” fossil reconstruction.
Political Stability and Economic Growth in Nigeria

The study empirically investigated the relationship between political stability and economic growth in Nigeria for the period 1999 to 2014 using the ARDL model approach. The result revealed a positive and significant relationship between political stability and economic growth both in the long run and in the short run. The study concludes that a stable political environment is an indispensable element for economic growth and therefore, the government of Nigeria should as a matter of necessity, identify the root causes of unstable political environment and try to mitigate its effects so as to ensure sustained growth in Nigeria.
Theoretical and Practical Decisions of Bankruptcy as one of Dynamic Alternatives in Company‘s Performance

The problems of company’s alternative develop-ment, its bankruptcy and bankruptcy prediction have become very relevant in Lithuania during the last dec-ades. According to the different authors, every bank-ruptcy is assessed as its local phenomenon as well as the macro economic appearance, which brings a lot of economic and social consequences for people who lose their jobs as well as for appropriate institutions. Theo-retical results of research are often integrated into the process of company’s administration, however the ris-ing number of bankruptcies shows that bankruptcy pre-diction is not assessed properly in the practical level of company’s management. The administration practice of failed companies in Lithuania shows that this process often determines negative results in the company and is very painful for its employees as well as for its creditors and owners. The changes of external conditions and the pressure that company experiences in the nowadays market economy often go the limits of the company’s management competence. Working companies face the global transformation, which is very specific, so it is not always possible to apply the traditional means of crisis management in their administration. Bankruptcy, as one of crisis development alternative in the company, is pos-sible to avoid properly estimating bankruptcy probabil-ity and applying prevention means in company’s per-formance in time. When bankruptcy mechanism is late, to start new activities or to reorganize the company is often impossible because of the short company’s re-serves. Bankruptcy prediction should be based on the continual observation and assessment of its financial state in order to notice the very first bankruptcy fea-tures, to define their reasons and to estimate their solu-tion possibilities. The article deals with the theoretical dynamic alternatives of crisis development in a com-pany. Bankruptcy features are analyzed applying dis-criminant analysis.
Developments in the Taxation of Corporate Profit in the OECD since 1965: Rates, Bases and Revenues

This paper describes developments in corporation taxes in the OECD over the last 40 years. It pays particular attention to the apparent divergence in the trends of the average statutory corporation tax rate and the average ratio of corporation tax revenues to GDP: the former has declined over time, while the latter has risen. It develops a simple framework for assessing the expected effect of the tax rate on tax revenues, and estimates the relationship using a panel of aggregate data for 20 OECD countries from 1965 to 2004, controlling for a measure of the tax base and other factors. There is only weak evidence of any relationship between the two. Evidence which does support a relationship is consistent with the finding of Clausing (2006) that the relationship is nonlinear, and that the implied revenue-maximising tax rate is likely to be low.
Reddening behaviors of young stellar objects in Spitzer/IRAC bands

We investigate the reddening behaviors of young stellar objects (YSOs) in the photometric system of the InfraRed Array Camera (IRAC) onboard the Spitzer Space Telescope. We constructed a couple of model extinction laws for the IRAC wavelength range that are composed of a power-law function and a 9.7 μm absorption bump by silicates. We then calculated reddened colors of the YSOs in 3 different evolutionary stages with various masses and disk inclinations by convolving the adopted model spectral energy distributions (SEDs) with the spectral response functions of the IRAC bands for KS-band extinction values of up to 8 mag. We find that the reddening vectors of YSOs in the [3.6]−[4.5] vs. [5.8]−[8.0] diagrams are considerably SED-dependent and can be highly nonlinear in some cases. Many YSOs show a “bluening” (as opposed to the reddening) in the [5.8]−[8.0] color owing to the 9.7 μm bump in the extinction law. Our findings imply that dereddening in a color–color or color–magnitude diagram involving the [8.0] band might be highly unreliable unless the SED of the source and the extinction law are at least approximately known.
Simulation of Vortex Ring Formation and the Effect of Piston VelocityProgram on the Formation Number

Vortex ring formation is a limited growth process. Upon reaching a non-dimensional formation number, the vortex ring pinches off and secondary vortices form in the trailing jet. However, since a larger vortex ring is associated with higher propulsive efficiency, it is desired to delay vortex ring pinch-off. In this study, a numerical model based on vortex sheet method was used to study vortex ring formation from a piston-cylinder apparatus, with the focus on the vortex ring pinch-off at formation number F. Studies on the various piston velocity programs showed that piston acceleration is able to delay the vortex ring pinch-off and the formation of secondary vortices. The delay is more significant when the vortex ring pinch-off occurs while the piston is accelerating. Acceleration of piston before a constant velocity period would still delay the vortex ring pinch-off, but to a much smaller extent.
Remediation of a copper mine soil with organic amendments: compost and biochar versus Technosol and biochar

The contamination produced by metal mining activities is a major environmental problem; for this reason, sustainable management strategies are required for remediating mine soils. The present study focused on the effect of applying organic amendments combined with vegetation in a settling pond soil of a depleted copper mine of Touro (Spain). Two different amendments were applied in different soil/substrate ratios: (1) a mixture made of Technosol and biochar and (2) a mixture of compost and biochar. A 3-month greenhouse experiment was carried out to evaluate the effect of both amendments and mustard plants on the chemical characteristics of the mine soil and the metal uptake by plants. The results showed that the addition of both amendments and planting mustards significantly increased soil pH as well as C and N soil concentrations. The treatments also reduced the CaCl2-extractable metal concentrations in the soil. However, the amendments increased the pseudototal concentration of Zn in the mixtures, since Zn was present in the Technosol and the compost used. Mustard plants extracted Ni from the soil amended with compost and biochar, and Zn from the soil amended with Technosol and biochar. These results suggest Brassica juncea L. is a potential candidate to revegetate mine soil for their tolerance to Ni and Zn.
