Water is an inescapable necessity for all forms of life on Earth. Therefore, both man-made reservoirs and natural reservoirs play critical roles for several purposes. Evaporation is an important factor that should be taken into account in the case of surface water reservoirs in hot and dry environments, since it can cause significant water loss. In order to estimate the water budgets of reservoirs, the hydrologists are typically using specifically developed computer models which take into account the effects of evaporation. An important step in this repetitive process is to provide an as accurate as possible calculation of the current water budget of reservoir under study. A novel system for the required water budget calculation is proposed in this paper, providing an automated, fast and accurate solution, requiring no human effort as it is based on an autonomous sensor-equipped mini-boat. First, the autonomous mini boat follows predefined trajectories at a reservoir and builds a bathymetric map (depth map) of it. Then, an onboard computer calculates the water budget of the reservoir. The proposed system is portable;as a result, a single system can periodically serve at several water reservoirs. Following the description of the main components of the proposed system, that is the autonomous navigation system and water budget calculation application, the performance of the navigation subsystem and the system as a whole is evaluated based on simulation studies.

This paper presents a system that is able to monitor the patient vital signs (Heart Rate, SPO 2 , NIBP, ECG, temperature and respiration rate) and send them continuously to the doctor's android phone device. The system enables multiple patients to be connected to the same doctor. Within the system, the health care professional may activate/deactivate any of the vital signs sensors. He can also set a prescription for the patient, schedule a meeting,... When bad activities are received, a message is directly sent to the doctor and to the patient relatives in order to alert them. Note that the Bluetooth connection is used to send/receive data between the patient platform and its android system. The tested results showed an almost error free system with an accuracy above 95% and a few milliseconds delay between the vital signs reading and their upload over the server.

Contemporary simulation technology for neuronal networks enables the simulation of brain-scale networks using neuron models with a single or a few compartments. However, distributed simulations at full cell density are still lacking the electrical coupling between cells via so called gap junctions. This is due to the absence of efficient algorithms to simulate gap junctions on large parallel computers. The difficulty is that gap junctions require an instantaneous interaction between the coupled neurons, whereas the efficiency of simulation codes for spiking neurons relies on delayed communication. In a recent paper [15] we describe a technology to overcome this obstacle. Here, we give an overview of the challenges to include gap junctions into a distributed simulation scheme for neuronal networks and present an implementation of the new technology available in the NEural Simulation Tool (NEST 2.10.0). Subsequently we introduce the usage of gap junctions in model scripts as well as benchmarks assessing the performance and overhead of the technology on the supercomputers JUQUEEN and K computer. © Springer International Publishing AG 2016.

The overwhelming acceptance of social media creates opportunities to learn about facts and events that are echoed in posts, tweets and messages uploaded by users. Analysis of these data can lead to interesting observations and conclusions. Of special importance are aspects related to temporal and dynamic nature of these findings. This paper presents a simple fuzzy-based approach of pre-processing and analyzing Twitter hashtags. The obtained fuzzy clusters are further examined in order to gain insight related to temporal trends and patterns of hashtags' popularity.

Automated decision systems for emboli detection is a crucial need since it is being done by visual determination of experts which causes excess time consumption and subjectivity. This work presents an emboli detection system using various dimensionality reduction algorithms on Doppler ultrasound signals recorded from both forward and reverse flow of blood transformed via Fast Fourier Transform (FFT), Discrete Wavelet Transform (DWT), and Dual Tree Complex Wavelet Transform (DTCWT). The combined forward and reverse DTCWT based features produced the highest performance when fed to SVMs classifier. As to compare dimensionality reduction algorithms, although PCA and LDA gave comparable accuracies, LDA has accomplished these accuracies only with two components due to its less than the number of classes' orthogonal projective directions limitation. SVMs yielded higher classification accuracies than k-NN with all considered dimensionality reduction methods since SVMs classifier is more robust to noise and irrelevant features. With the ability to localize well both in time and frequency, wavelet transform based extracted features gave higher overall classification accuracies than FFT with the more stable classifier SVMs. Additionally, DTCWT accuracies are higher with SVMs than those of DWT since it also has the ability of being shift-invariant. © Springer International Publishing Switzerland 2014.

Work-life balance (WLB) can be described as the fulfillment of the duties and responsibilities of workers in their private and business lives in addition to minimizing the conflicts between business and private lives. This can be achieved with self-scheduling of workers only by allocating fair time for private life as well as work life. In enterprises, the workers demand, starting time and working hours of a job can vary according to the nature of the job done and quantitative and qualitative characteristics of workers. The main idea of this study is to develop a method which is balancing between work and private life by considering a self-scheduled working plan regulated systematical as far as weekly or monthly determining qualities and quantities of doctors and nurses to fulfill the needs for different departments of a hospital, considering the number of patients at different hours of a day. In this study, a prototype software was developed to fulfil the requirement of workers and enterprises for balancing work-life considering demands of workers and employers. The developed software can record the numbers and attributes of required personnel to a database according to daily, weekly or monthly demands. The current numbers and attributes of workers then requirements of the employer are entered into the database. Then, workers can choose their work times by considering day and hours from this database. The developed software reconciles the needs of the enterprise and personnel demands with synchronizing the needed working hours of enterprise and selection of personnel. Work assignments are done by personnel requests. Personnel decides their own working time so that monthly and weekly schedules can be obtained. The software is coded in Ms C# programming language and is applied in a hospital. The personnel demands which changes monthly, weekly and different working hours in a day can be assigned by considering doctors and nurses requests' with the help of developed so

Solving multi-choice multi-objective transportation problem: a utility function approach

引用

Journal of Uncertainty Analysis and Applications 2014年第1期2卷 1-20页

作者： Gurupada Maity Sankar Kumar Roy Department of Applied Mathematics with Oceanology and Computer Programming Vidyasagar University Midnapore India

This paper explores the study of multi-choice multi-objective transportation problem (MCMTP) under the environment of utility function approach. MCMTP is converted to multi-objective transportation problems (MOTP) by transforming the multi-choice parameters like cost, demand, and supply to real-valued parameters. A general transformation procedure using binary variables is illustrated to reduce MCMTP into MOTP. Most of the MOTP are solved by goal programming (GP) approach. Using GP, the solution of MOTP may not be satisfied all the time by the decision maker (DM) when the proposed problem contains interval-valued aspiration level. To overcome this difficulty, here we propose the approaches of revised multi-choice goal programming (RMCGP) and utility function into the MOTP and then compared the solution between them. Finally, numerical examples are presented to show the feasibility and usefulness of our paper.
