IT Management Flexibility Concept for Higher Education

The rapid development of technology influences the changing culture of various aspects of the organization. This results in a paradigm shift in many areas of the organization, including in higher education. Changes have taken place in the implementation of the core and support processes in the universities. Cultural changes occur in the teaching and learning processes as well as in the administration of higher education. Universities are required to respond and be flexible to change, which needs planning and management. Unplanned and unproperly managed changes may cause a decrease in efficiency and productivity, especially in higher education. Discussion of flexibility generally relates to manufacturing companies. This paper aimed to identify factors of IT management flexibility needs in higher education by adopting supply chain flexibility concept. Supply chain flexibility is oriented at improving the quality of distributing and ordering goods while the IT management flexibility concept is oriented at improving the quality of service at universities. The research phase includes: identifying needs, envisioning, and planning solutions. The results show that communication, IT leadership, human resource, and regulation are essential factors in increasing IT management flexibility in higher education.
Nonconvex Medium-Term Hydropower Scheduling by Stochastic Dual Dynamic Integer Programming

Hydropower producers rely on stochastic optimization when scheduling their resources over long periods of time. Due to its computational complexity, the optimization problem is normally cast as a stochastic linear program. In a future power market with more volatile power prices, it becomes increasingly important to capture parts of the hydropower operational characteristics that are not easily linearized, e.g., unit commitment and nonconvex generation curves. Stochastic dual dynamic programming (SDDP) is a state-of-the-art algorithm for long- and medium-term hydropower scheduling with a linear problem formulation. A recently proposed extension of the SDDP method known as stochastic dual dynamic integer programming (SDDiP) has proven convergence also in the nonconvex case. We apply the SDDiP algorithm to the medium-term hydropower scheduling (MTHS) problem and elaborate on how to incorporate stagewise-dependent stochastic variables on the right-hand sides and the objective of the optimization problem. Finally, we demonstrate the capability of the SDDiP algorithm on a case study for a Norwegian hydropower producer. The case study demonstrates that it is possible but time-consuming to solve the MTHS problem to optimality. However, the case study shows that a new type of cut, known as strengthened Benders cut, significantly contributes to close the optimality gap compared to classical Benders cuts.
Adaptive Robust Short-Term Planning of Electrical Distribution Systems Considering Siting and Sizing of Renewable Energy Based DG Units

Short-term planning is a decision-making process that aims at ensuring proper performance of electrical distribution systems (EDSs) within a short period of time. In recent years, this process has faced a significant challenge due to the integration of renewable energy based technologies. To handle such complicated planning problem most suitably, sophisticated algorithms are required. This paper proposes a mixed-integer linear programming model to find the optimal short-term plan of EDSs considering siting and sizing of capacitor banks and renewable energy sources, conductor replacement of overloaded circuits, and voltage regulators allocation. Besides considering the economic aspects, the environmental issues are also considered to promote a low carbon emission system. To address the uncertainties of electricity consumption and renewable energy output power, a two-stage robust optimization model is used, and to handle this model more efficiently, the column and constraint generation algorithm is applied. A 135-node distribution system is studied under different conditions to assess the performance of the proposed approach. Results show that the planning actions, for each case study, improve the efficiency of EDS and mitigate the pollutant emissions at the distribution level.
Robust Line Hardening Strategies for Improving the Resilience of Distribution Systems With Variable Renewable Resources

Line hardening refers to strengthening certain distribution lines that will not be subject to outages during extreme conditions. Line hardening provides a resilient solution in the case of major faults in a radial or meshed distribution system. We propose a robust optimal line hardening method coupled with multiple provisional microgrids to improve the distribution system resilience against worst N-k contingencies. In this case, provisional microgrids, which are interconnected by hardened liens, do not have the islanding capability and depend on the supply provided by one or more electrically connected microgrids for islanding purposes. A trilevel optimal model is considered with the objectives of minimizing the costs of line hardening and the operation of multiple islanded provisional microgrids, which could include the cost of load shedding in each provisional microgrid considering the worst N-k contingencies. Specifically, a two-stage robust optimization model is formulated and Benders decomposition (BD) algorithm coupled with iterative relaxation procedure (IRP) is developed to enable the tractable computation. In our work, the master problem determines line hardening strategies and the subproblem discovers the impact of the worst N-k contingencies corresponding to the optimal operation of reformed provisional microgrids. The second-stage which includes the max–min subproblem is solved efficiently using linearization techniques, duality theory, and IRP. Our numerical results for the IEEE distribution test systems validate the effectiveness of the proposed model and reveal that distributed generation is critical in increasing the resilience of distribution systems corresponding to the worst N-k contingencies in provisional microgrids.
Revalidation of smear negative tubercular infection by conventional and by PCR applications

IS6110 sequence based Polymerase Chain reaction (PCR) was compared with conventional bacteriological techniques in the laboratory diagnosis of Mycobacterium tuberculosis (MTB). A retrospective study involving one hundred and twenty six, non-repeated clinical isolates patients being investigated for tuberculosis. The samples were also processed for Ziehl-Neelsen (ZN) staining for acid fast bacilli (AFB) and culture for MTB. All the samples were processed for PCR amplification with primer targeting 123 bp fragments of insertion sequences IS6110 of M. tuberculosis complex (MTC) and the sensitivity of PCR was analyzed. Of the 126 patients, 100% and 97.3% were smears and culture positive for MTB respectively. Using culture as the gold standard, the overall sensitivity of PCR was 97.62%, and for either positive or either negative clinical isolates it was 97.06%% and 92.31%, respectively. The current study evaluated a PCR assay for the detection of MTC strains by targeting the IS 6110 insertion element. This PCR has emerged as a rapid, reliable and a potent tool in establishing the diagnosis of tuberculosis with higher sensitivity than ZN microscopy and greater alacrity than culture.
A Modified PWM Scheme to Improve Performance of a Single-Phase Active-Front-End Impedance Source Inverter

Impedance source inverters (ISIs) are gaining attention due to features such as single-stage conversion, buck-boost capability, and inherent shoot-through protection. To maintain the required ac output voltage, typically ISIs are operated at a higher dc-link voltage due to constrained modulation index. This also increases voltage stress across capacitors and switches of the converter. This voltage stress is approximately double compared to that of voltage source inverter with preboost stage (Boost-VSI). To mitigate this problem, a new pulsewidth modulation (PWM) scheme for the active-front-end based ISIs (AFE-ISIs) is proposed. The proposed scheme enables the ISIs to produce high ac gain with lower voltage stress across the capacitor and switches. In other words, the proposed scheme blends the advantages of Boost-VSI into ISIs. With the new PWM scheme, there are also reductions in output voltage total harmonic distortion, switching frequency ripple in the inductor current, and power loss in the converter. A prototype of the current-fed switched inverter, an AFE-ISI, is designed, and the proposed PWM scheme is implemented. Experimental results obtained are in accordance with the proposed theory and show that the voltage stress has reduced from 325 V to 203 V for an ac output of 110 V.

An 8-Gs/s 12-Bit TIADC System With Real-Time Broadband Mismatch Error Correction

High sampling speed can be achieved using multiple analog-to-digital converters (ADCs) based on the time-interleaved analog-to-digital conversion (TIADC) technique. Various types of methods were proposed to correct the mismatch errors among parallel ADC channels in TIADC systems, which would deteriorate the system performance. Traditional correction methods based on digital signal processing have good performance, however, often only for input signals limited in a narrow frequency band. In this paper, we present our recent work on the design of an 8-Gs/s 12-bit TIADC system and the implementation of real-time mismatch correction algorithms in field programmable gate array devices, over a broadband of input signal frequencies. Tests were also conducted to evaluate the system performance, and the results indicate that the effective number of bits is enhanced to be better than 8.5 bits (<800 MHz) and 8 bits from 800 MHz to 1.6 GHz after correction, almost the same with that of the ADC chip employed.
The MARTA (Muon Array With RPCs for Tagging Air Showers) Front-End Acquisition System

The design and performance of a new front-end acquisition system is presented in this paper. It was developed to be used with muon array with resistive plate chamber (RPCs) for tagging air showers (MARTA’s) RPC detectors that measure the muonic component of cosmic ray air showers. The system is hybrid and capable of counting active channels and performing a charge measurement. It is low power (1.43 W per 64 channels), compact ( $21.6 \times 14.4\,\,\mathrm {cm^{2}}$ per 64 channels), stable, and reliable to comply with the strict demands of field operation associated with experiments that measure air showers. The front-end is based on an application-specified integrated circuit [Multi Anode Read-Out Chip (MAROC)] with 64 input channels, which is responsible for the digitization of the RPC signals. While a simple threshold measurement is applied after a fast shaper to count particles, the charge measurement is performed by an analog to digital converter that reads the peak of a slow shaper. An field-programmable gate array is responsible for control of all the digital part which includes storing the MAROC outputs and sending them to a Central Unit [via low voltage differential signal (LVDS)] or PC (via USB). Both the count and charge measurement performance are assessed. The threshold efficiency curve is measured for different temperatures. For all the conditions tested, the efficiency is 100% for charges higher than 52 fC. The overall efficiency to detect muons is studied by placing an RPC between a hodoscope and comparing the efficiency of the front-end with another established data acquisition system. The efficiency results are consistent within the statistical uncertainties of the measurements showing that the MARTA front-end does not introduce unwanted inefficiencies in the setup. The charge measurement is tested in the laboratory using a signal generator. Different shaping conditions and input charges are used to study the waveform of the slow shaper. A linear dependence between input charge and the value measured by the MAROC was found and taken as the calibration curve for the particular channel tested.

Hyperbolic-weighted centroid Indoor Location Algorithm based on Kalman Filter

The ultra-wideband(UWB) signal is affected by systematic measurement error and Not-Line-of-Sight(NLOS) error when it propagates in complex indoor environment, which leads to poor positioning accuracy and stability. In order to reduce the influence of error on the accuracy of positioning results, a Hyperbolic-weighted centroid algorithm based on Kalman Filter is proposed in this paper. The method is based on the time difference of arrival(TDOA) location model. The measured value of the TDOA distance difference is first filtered by Kalman Filter, and then the obtained results are used as the input of the Hyperbolic location algorithm to acquire the initial solution. For further offsetting the effect of error on positioning accuracy, a weighted centroid technique is applied. We evaluate the performance of the proposed method in both simulation and experimental results. The experimental results show that the position accuracy is effectively improved by the algorithm. When the measurement error satisfies the Gaussian distribution and the standard deviation is 0.1 m, the Root Mean Square Error(RMSE) of the location results is about 11 cm.
Effectiveness of primary care interventions for weight management in children and adolescents: an updated, targeted systematic review for the USPSTF

CRD summary This review examined benefits and harms of behavioural and pharmacological weight-management interventions for overweight and obese children and concluded that medium to high intensity behavioural interventions appeared to be beneficial. Potential for language bias and clinical variation and methodological weaknesses in the included studies mean that caution is required when judging the reliability of the authors' conclusions.
Logical Encoding of Argumentation Frameworks with Higher-Order Attacks

We propose a logical encoding of extended abstract argumentation frameworks, that is frameworks with higher-order attacks (i.e. attacks whose targets are other attacks). Our purpose is to separate the logical expression of the meaning of an attack (simple or higher-order) from the logical expression of acceptability semantics. We consider semantics which specify the conditions under which the arguments (resp. the attacks) are considered as accepted, directly on the extended framework, without translating the original framework into a Dung's argumentation framework. We characterize the output of a given framework in logical terms (namely as particular models of a logical theory). Our proposal applies to the particular case of Dung's frameworks, enabling to recover standard extensions.
Malnutrition, dietary diversity, morbidity and associated factors among schoolchildren in Kibwezi District, Kenya

In Kenya, information on the nutritional status of schoolchildren is scanty. This study assessed malnutrition levels (stunting, underweight, thinness, and anemia and serum RBP levels), dietary diversity and morbidity among children in Kibwezi district and served to provide baseline information for a randomized controlled trial of the effect of provitamin A biofortified cassava on vitamin A status of primary school children in Kenya. A cross-sectional survey was conducted in three primary schools selected based on an estimated prevalence of Vitamin A Deficiency of 50%, size of the school and willingness to participate. Information on household socio-economic and demographic characteristics and children’s morbidity burden was collected using pre-tested questionnaires and trained interviewers. A fourteen day recall period and a 24-hour recall period was used for morbidity and individual diversity score respectively. Blood for RBP and haemoglobin analysis was drawn by qualified and trained technicians. Descriptive statistics were computed for demographic and socio-economic data. Logistic regression and bivariate correlation analyses were performed to establish relationships. A P-value of 0.05). The main source of income for the household was a significant predictor of individual dietary diversity (OR=1.4; 95%CI=1.3, 2.6). Children from households with permanent employment being main source of income were likely to have a higher IDDS. Of the 423 children, 22.0% were sick in the two weeks preceding the survey of which only 52.2% sought medical intervention. The mean number of times a child was sick in the two weeks was 1.06 (±0.25) times while the mean number of days per occasion of illness was 3.15 (± 2.4) days. Educational level of the caregiver, hemoglobin and dietary diversity score were strong predictors of morbidity status of a child (p<0.05). The study concludes that anemia is of mild public health significance among schoolchildren. Malnutrition measured by stunting, underweight and thinness is widespread among the schoolchildren. There is poor diet quality evidenced by low individual dietary diversity. Educational levels of the caregiver and dietary diversity are a determinant of child morbidity. Moreover, there is a high rate of disease burden among schoolchildren.
Kpn-boats, Punt Trade, and a Lost Emporium

One result of the study of Thutmose I's Kush campaign and his Tombos Inscription at the 3rd Cataract has been the realization that early in the 18th Dynasty the Egyptians had established a presence in the territory at the head of the 4th Cataract, the lands around Abu Hamed and Kurgus (fig. I). 1 Within the Tombos text Thutmoses I claimed to have built a frontier fortress, presumably in this region, after his conquest. Over time there may have been a complex of forts situated along the North-South overland trade route on the east side of the Nile between
Variabilité des pratiques funéraires et différenciation sociale dans le Néolithique ancien danubien

Au debut des annees soixante-dix, les resultats de la necropole de Nitra ont conforte l'idee d'une societe rubanee faiblement differenciee. Le corpus des vestiges funeraires publies du Neolithique ancien danubien s'est depuis tres largement enrichi. On possede aujourd'hui des series significatives pour toute la duree du Rubane et pour l'essentiel de son aire de repartition. Leur etude montre que le modele elabore sur la base des donnees recueillies a Nitra n 'a de validite que dans un cadre geographique et chronologique bien circonscrit. Les grandes necropoles decouvertes depuis 1960 de la Baviere a la Meuse illustrent l'existence d'une evolution graduelle vers une societe plus complexe, avec un degre de differenciation plus eleve aussi bien horizontalement que verticalement. Les necropoles les plus tardives se caracterisent par l'existence d'un petit groupe de tombes tres riches qui se detachent nettement du lot. Au sein de ce groupe, la presence recurrente de tombes d'enfants d'ou n'est exclue aucune des categories de mobilier presentes dans les tombes d'adultes suggere fortement l'existence d'une transmission des statuts par l'heredite. Dans la seconde moitie du Neolithique ancien, ce modele cohabite avec celui de Nitra, qui continue de regir le sort de la grande masse de la population. Cette evolution dans le sens d'un accroissement sensible des inegalites est corroboree par les changements qui interviennent dans le domaine de l'habitat. Comme l'attestent les nombreux indices de morts violentes recueillis ces dernieres annees, la societe plus complexe qui en resulte semble dechiree par de profondes contradictions internes qui nous conduisent tres loin de l'image bucolique qui demeure l'arriere-plan implicite de la plupart des syntheses consacrees a la sociologie du Neolithique ancien danubien.
Teaching Functional Use of an iPod-Based Speech-Generating Device to Individuals with Developmental Disabilities

Anecdotal reports suggest that individuals with developmental disabilities who lack speech may be enabled to communicate through the use of a new iPod-based communication device. However, there appear to be limited empirical data demonstrating successful use of this new device by such individuals. This study was designed to provide empirical evidence on acquisition and functional use of an iPod-based communication device. Three individuals with developmental disabilities participated in baseline, acquisition-training, post-training, and follow-up phases that were staggered in a multiple-probe across participants design. Acquisition-training focused on teaching participants to request snacks, or snacks and toys, by selecting graphic symbols on an iPod Touch® with Proloquo2Go™ software. Graduated guidance, time delay, and differential reinforcement procedures were successful in teaching functional use of the iPod-based system to two of the three participants. These preliminary results support the use of this new iPod-based communication system for some individuals with developmental disabilities.
