Analyzing and Predicting Career Specialization using Classification Techniques

Nowadays, academic institutions conduct studies to attain quality and excellence in student academic performance through Data Mining tools. This paper explores various classification techniques in predicting graduates' career specialization. The data sets used were obtained from Bulacan State University Sarmiento Campus’ Information Technology graduates from 2013 to 2016. From these data, a model was created using Naïve Bayes, J48, Random Forest, and Support Vector Machine classification algorithm, with 18 attributes. Among the models built, Naïve Bayes and Random Forest algorithm yielded better accuracy rating, and acceptable ROC and RMSE values. Performance of students per subject area was also determined, and based on this; students perform satisfactorily in both soft and technical skills manifested in the highly satisfactory performance on the Internship course. However, there were few graduates who pursue a career in Networking, and measures must be undertaken to elevate performance in early Programming and Networking courses.
Techniques for Estimating the Age and Growth of Molluscs: Gastropoda

ABSTRACT Gastropoda is a large and diverse group of the Mollusca found almost ubiquitously throughout freshwater, terrestrial, and marine habitats. Marine gastropods often support large commercially important fisheries, many of which are facing concerns over sustainability as landings have increased and populations have dwindled over recent decades. For effective fishery management, the inclusion of an age estimation technique is vital to understand growth rates and population structures to feed into analytical stock assessments. Unlike many bivalve species, gastropods are often difficult to age, especially those which exhibit planispiral coiling of their shells, as no single growth axis can be easily uncovered via sectioning. This review covers a range of techniques that can be used to estimate age and growth rates for many marine gastropod species. Although there is no universal aging technique to cover all species, individual techniques have varying success levels for different species groups.
Testing the Smooth Driving of a Train Using a Neural Network

This article deals with the extraction of a new original parameter to characterize a railway traffic driving smoothness indicator, and its investigation is based on data obtained from a neural train emulator. This indicator of driving smoothness is an example of the sustainable value of control command and signaling technology. The pro-social and pro-environmental aspects of smooth driving are indicated and the article proposes the introduction of a new indicator for assessing the quality of rail traffic, taking into account traffic on a micro scale—the driving smoothness of a single train (also called driving flow), derived from a parameter identified in the literature—and traffic smoothness (also called traffic flow), describing traffic quality on a macro scale. At the same time, the concept of a neural train emulator is presented, providing input data to determine the value of the proposed indicator for different train models and track systems in order to test the indicator’s properties. The concept proposes the structure of an artificial neural network, the technique of obtaining test data sets and the conditions of training the network as well. An emulator based on the neural network enables the simulation of train driving, taking into account its nonlinearity and data acquisition for indicator research.
Selecting indicator species for biodiversity management

Indicator species are frequently used for biodiversity management but whether indicator species selection is explicit about their ability to improve management decisions remains unclear. We reviewed the scientific literature to assess whether existing methods for selecting indicator species account for the following five monitoring and management “decision factors”: objectives, constraints, actions, uncertainties, and biodiversity outcomes. Of the selected studies, most focused only on improving monitoring efficiency rather than on management effectiveness, potentially leading to ineffective indicators for decision making; only 21% of the studies explicitly accounted for management objectives and actions. Crucially, 94% of the reviewed studies and one-half of all indicator selection methods overlooked constraints (eg budgets), as well as uncertainties in indicator responses to management. To improve selection of indicator species, we suggest a systematic approach using key concepts from structured decision making. This approach facilitates explicitly evaluating management outcomes as part of the indicator species selection process and allows for the review of indicator choices over time to improve future monitoring and management decisions.

Assessment of Radiation-Induced Secondary Cancer Risks In Breast Cancer Patients Treated with 3D Conformal Radiotherapy

Introduction: In the current study, radiation-induced secondary cancers risks (SCRs) have been evaluated in irradiated organs following three-dimensional conformal radiation therapy (3D-CRT) of breast cancer using the BEIR (Biological Effects of Ionizing Radiation) VII models. Material and Methods: Sixty patients with left-sided breast cancer were chosen for this study and who were treated with a total breast dose of 50 Gy in 2 Gy fractions. Differential dose volume histograms (dDVHs) were retrieved and values of mean organs dose were computed. SCRs to the heart, ipsilateral lung, liver, thyroid, and contralateral were estimated using both excess relative risk (ERR) and excess absolute risks (EAR) models as proposed by BEIR VII committee of the U.S National Academy of Sciences.Average values of organ dose to these 60 patients were 6.8, 15.9, 3.7, 4.5 and 1.5 Gy in the thyroid, ipsilateral lung, contralateral breast, heart, and liver, respectively. Results: From the BEIR VII models, ERR incidence was estimated to be 21.2, 5.0, 1.6 and 1.4 Gy-1 for the ipsilateral lung, thyroid, heart, and liver, respectively. EAR for cancer incidence was calculated as 105, 45.8, 15.8 and 4.35 Gy-1 for these same organs. Conclusion: The study showed SCRs quantitatively to various organs for patients with breast cancer who received 3D-CRT. We found that 3D-CRT treatment is associated with a relatively high SCR in the lung.
Comparison of pressurized water reactor core characteristics for 100% plutonium-containing loadings

The large quantities of reactor-grade (RG) and weapons-grade (WG) Pu accumulated worldwide could be reduced by employing 100% mixed-oxide (MOX) cores in light water reactors. The buildup of new Pu from the U present in the MOX, however remains disadvantageous from the viewpoint of inventory reduction and also enhances the need for multiple recycling. A more effective way would be to use U-free fuel so that no new Pu is produced. A comparison is made, from the physics design viewpoint, between the potential and the possible difficulties for two different types of Pu-burning pressurized water reactor cores, namely, 100% MOX and 100% uranium-free Pu fuel. The latter employs ZrO2 as inert matrix and Er2O3 as burnable poison. In each case, RG and WG Pu have been considered separately. The characteristics of the four different cores have been studied on the basis of three-dimensional calculations for an equilibrium cycle, a real-life UO2-fueled core being considered as reference for comparison purposes. For all four Pu-burning cases, it appears possible to design a four-region core with a natural cycle length of more than 300 days. For the 100% MOX cores, the Pu mass is reduced during irradiation by 35% of the initial Pu inventory. For the U-free cores, the consumption is about twice as much, i.e., 60% for the RG-Pu fuel and over 70% for the WG-Pu core. The reactivity balance in going from hot full power to hot zero power conditions shows that while the 100% MOX core with RG Pu would need more effective control rods, both types of U-free cores have larger shutdown margins than the reference case. Consideration of the reactivity coefficients indicates that a steam-line-break accident could be more problematic in the MOX core with RG Pu than in the other cases. The rod ejection transient should be safe because the maximum inserted worth of a control rod is 0.5 $. More detailed investigations of transient behavior-particularly for the U-free cores-are needed, the current study having considered feasibility mainly from the viewpoint of static physics considerations
Prey perception mechanism determines maximum clearance rates of planktonic copepods

The ecological consequences of “sit‐and‐wait” (ambushing) vs. “searching” (active feeding) foraging strategies are not well‐understood in marine plankton food webs. We determined the maximum clearance rates of ambush and active feeders to evaluate the trade‐off between foraging gain and predation risk associated with the main foraging strategies in planktonic copepods. We show that maximum clearance rates are similar among feeding behaviors for motile prey but one order of magnitude lower for ambush than for active feeders toward nonmotile prey. The prey size spectrum is narrower and toward relatively larger prey in ambushers compared with active feeders. Prey detection in ambushers relies on the hydrodynamic disturbances and is inefficient toward nonmotile prey but highly efficient for large motile prey. The effective prey perception mechanism in ambushers compensates for the lower prey encounter velocity in ambush feeding copepods compared with active feeding copepods. Therefore, ambushers are more restricted in target prey than active feeders and prey perception mechanism determines the efficiency of planktonic copepod foraging strategies. The lower clearance rates of ambush feeders on nonmotile prey is compensated for by a lower predation risk, which can partially explain the coexistence of both “high‐gain & high‐risk” (active feeders) and “low‐gain & low‐risk” (ambush feeders) foraging strategies in marine plankton food webs.
Employing the RE-AIM Framework to Evaluate Multisport Service Organization Initiatives

Abstract The evaluation of Multisport Service Organization (MSO) initiatives can result in a greater understanding of factors related to their success. The RE-AIM framework is an evidence-informed framework for comprehensive evaluations but has not been employed in MSO contexts. The purpose of this study was to develop a template of operationalized RE-AIM indicators for MSO initiatives and to provide a case-study of its application with an existing initiative – True Sport. This template can enable MSO initiatives to leverage existing data for hierarchical and pragmatic evaluations and is generalizable for other sport contexts. Recommendations are advanced for practitioners undertaking sport program evaluations.

Antioxidant Potential of Ziziphora Clinopodioides Lam: A Narrative Review

ARTICLE INFO ABSTRACT Submitted: 2 Feb 2020 Reactive oxygen species (ROS) are generated by many redox processes that normally occur in the metabolism of aerobic cells. They are highly reactive and harmful to normal cells. If not eliminated, they can damage important molecules, such as DNA and proteins. These harmful effects of free radicals can be blocked by antioxidants, which scavenge the free radicals and detoxify the organism. Plants and plant-derived products contain a wide range of phytochemicals, such as antioxidants, which are thought to have a protective role against the risk of oxidative stress-related diseases. Oxidative stress is an important contributor to the pathophysiology of a variety of pathological conditions such as arteriosclerosis, cancer, gastrointestinal tract disorders, rheumatism, diabetes mellitus, cardiovascular diseases, nephritis, neurodegenerative disease, and inflammatory injury. Recently, interest has considerably increased in finding naturally occurring antioxidants to replace synthetic antioxidants, which were restricted due to their adverse reactions such as carcinogenesis. Natural products have been the basis to treat some human diseases. There is emerging interest in the use of naturally occurring antioxidants for the management of a number of these pathophysiological conditions. Among the various natural sources, endemic medicinal plant species are of particular interest because they may be used for producing raw materials or preparations containing phytochemicals with significant antioxidant capacities and possible health benefits. Ziziphora Clinopodioides, known as Kakuti-e kuhi, Ankh, Lip vanilla, and mountain mint, is a wild flowering plant of Lamiaceae family. It is native to the parts of Iran and Iraq. In traditional medicine of Iran, this plant has been used to treat stomach and gastrointestinal pain, inflammatory, and cardiovascular disease, asthma, cough, bronchitis, insomnia, colds, flu, and other infectious diseases. In this paper, published antioxidant activities of Z. Clinopodioides were reviewed. Accepted: 30 Mar 2020 Published: 31 Jun 2020
Higher-Order Spectra Analysis-Based Diagnosis Method of Blades Biofouling in a PMSG Driven Tidal Stream Turbine

Most electrical machines and drive signals are non-Gaussian and are highly nonlinear in nature. A useful set of techniques to examine such signals relies on higher-order statistics (HOS) spectral representations. They describe statistical dependencies of frequency components that are neglected by traditional spectral measures, namely the power spectrum (PS). One of the most used HOS is the bispectrum where examining higher-order correlations should provide further details and information about the conditions of electric machines and drives. In this context, the stator currents of electric machines are of particular interest because they are periodic, nonlinear, and cyclostationary. This current is, therefore, well adapted for analysis using bispectrum in the designing of an efficient condition monitoring method for electric machines and drives. This paper is, therefore, proposing a bispectrum-based diagnosis method dealing the with tidal stream turbine (TST) rotor blades biofouling issue, which is a marine environment natural process responsible for turbine rotor unbalance. The proposed bispectrum-based diagnosis method is verified using experimental data provided from a permanent magnet synchronous generator (PMSG)-based TST experiencing biofouling emulated by attachment on the turbine blade. Based on the achieved results, it can be concluded that the proposed diagnosis method has been very successful. Indeed, biofouling imbalance-related frequencies are clearly identified despite marine environmental nuisances (turbulences and waves).

Seqpare: a novel metric of similarity between genomic interval sets

Summary Searching genomic interval sets produced by sequencing methods has been widely and routinely performed; however, existing metrics for quantifying similarities among interval sets are inconsistent. Here we introduce Seqpare, a self-consistent and effective metric of similarity and tool for comparing sequences based on their interval sets. With this metric, the similarity of two interval sets is quantified by a single index, the ratio of their effective overlap over the union: an index of zero indicates unrelated interval sets, and an index of one means that the interval sets are identical. Analysis and tests confirm the effectiveness and self-consistency of the Seqpare metric. Availability https://github.com/deepstanding/seqpare Contact jf.xtable@gmail.com
A Kinematic Collision Box Algorithm Applied for the Anti-Collision System of Offshore Drilling Vessels

With the advances in technology and the automation of drilling platforms, the Anti-Collision System (ACS) has appeared as an affordable technology, which is intended to keep equipment on the drilling floor working harmoniously and to prevent the potential hazards associated with accidents. However, the specialty of the machinery on the drilling floor requires a distinguished structure for the ACS and a reliable collision-avoidance algorithm, which is not similar to any algorithm in other applications, such as automobiles and robotics. The aim of this paper is to provide a comprehension of the configuration of an ACS in an Integrated Drilling System and to develop a practical anti-collision algorithm that can be applied to the machine arrangement for an offshore drilling operation. By analyzing the motions and using kinematic parameters, such as the speed and deceleration information of drilling equipment, a kinematic collision box algorithm is developed to eliminate the limitation of conventional algorithms. While the conventional collision-avoidance algorithm uses a collision box with fixed size, the kinematic collision box algorithm uses a collision box with a flexible scale that can be correspond to the velocity and deceleration rate of the equipment. Several operating scenarios are simulated by a visual model of ACS to authenticate the functionality of the proposed algorithm. The operation of the top drive is an outstanding scenario. Only 2.25 s are required to stop the top drive from its maximum velocity, and a conventional algorithm uses this number to create a fixed bounding box. Also, the kinematic collision box algorithm uses the real-time data of velocity and acceleration to adjust the scale of the bounding box when the speed of the top drive increases from 0 to its maximum value. The simulation result illustrates the reliability and advances of the kinematic collision box algorithm in performing the collision-avoidance function in ACS compared to the conventional algorithm.
Conductivity gradient focusing by pervaporationand osmosis-induced fluxes

It is possible to perform conductivity gradient focusing (CGF) with a conductivity gradient caused by pervaporation- or osmosis-induced fluxes. This is concluded from results obtained from a theoretical exploration and the results from experiments with glass microchannels with a PDMS roof. A minimal concentration factor of 28.6 was observed at experiments that proved that pervaporation flux was created in the channels. The flow velocity that was reached was at least 5.4. 10-6 m s-1. CGF experiments showed that concentrating of species with this CGF method is possible, however the created concentration peaks were instable and more study is necessary to improve the stability. Indications are found that separation with this CGF method is possible. This deserves more study. Finally it is recommended to do more study at absorption and adsorption of species in or at PDMS.
New Records of Dactylobiotus parthenogeneticus Bertolani, 1982 Provide Insight into Its Genetic Variability and Geographic Distribution

In sediment samples collected from three distinct European locations (United Kingdom, France, Poland), populations of Dactylobiotus parthenogeneticus were found. The original description of this species was based solely on the morphology observed with light microscopy and later supplemented by some additional SEM data of the buccal apparatus and DNA sequences of 18S rRNA and COI. Here we provide an updated description of the species by means of integrative taxonomy. The description comprises a comprehensive set of morphometric and morphological data from light and scanning microscopy as well as nucleotide sequences of three nuclear (18S rRNA, 28S rRNA, ITS-2) and one mitochondrial (COI) fragments. Our analysis of haplotype diversity confirmed our morphological identification and showed that D. parthenogeneticus is widely distributed in Europe.
