Diurnal cycle of surface energy fluxes in high mountain terrain: High‐resolution fully coupled atmosphere‐hydrology modelling and impact of lateral flow

Water and energy fluxes are inextricably interlinked within the interface of the land surface and the atmosphere. In the regional earth system models, the lower boundary parameterization of land surface neglects lateral hydrological processes, which may inadequately depict the surface water and energy fluxes variations, thus affecting the simulated atmospheric system through land‐atmosphere feedbacks. Therefore, the main objective of this study is to evaluate the hydrologically enhanced regional climate modelling in order to represent the diurnal cycle of surface energy fluxes in high spatial and temporal resolution. In this study, the Weather Research and Forecasting model (WRF) and coupled WRF Hydrological modelling system (WRF‐Hydro) are applied in a high alpine catchment in Northeastern Tibetan Plateau, the headwater area of the Heihe River. By evaluating and intercomparing model results by both models, the role of lateral flow processes on the surface energy fluxes dynamics is investigated. The model evaluations suggest that both WRF and coupled WRF‐Hydro reasonably represent the diurnal variations of the near‐surface meteorological fields, surface energy fluxes and hourly partitioning of available energy. By incorporating additional lateral flow processes, the coupled WRF‐Hydro simulates higher surface soil moisture over the mountainous area, resulting in increased latent heat flux and decreased sensible heat flux of around 20–50 W/m2 in their diurnal peak values during summertime, although the net radiation and ground heat fluxes remain almost unchanged. The simulation results show that the diurnal cycle of surface energy fluxes follows the local terrain and vegetation features. This highlights the importance of consideration of lateral flow processes over areas with heterogeneous terrain and land surfaces.
Investigation of the effect of selected edible and medicinal plants on in-vitro blood coagulation profile

Anticoagulation therapy represents a mainstay of treatment and prevention of cardiovascular diseases which are the leading causes of mortality worldwide. In addition, several case reports of spontaneous bleeding occurred linking the consumption of many dietary supplements during treatment with anticoagulants or in postoperative patients. This prompted our study which is conducted on eleven well-known Egyptian medicinal plants to highlight their effect on blood coagulation profile using Prothrombin time (PT) and activated partial thromboplastin time (aPTT) tests. Some of these plants showed interesting results that need more in-depth evaluation of their anticoagulant activity as Hibiscus sabdarifa calyx for its effect on PT. In addition, extracts of Trifolium alexandrinum aerial parts and Pimpinella anismum fruit were proved to affect aPTT. Post operative or cardiovascular patients using herbal supplements should be cautioned about food-drug or herb-drug interactions and to adjust their herbal medication regimen before surgery.
FPGA Implementation of Mutual Authentication Protocol for Medication Security System

Medication safety administration is a complicated process involving the information of patients, drugs, and data storage. The sensitive data transmitted through wireless sensor networks (WSNs) from Internet of things (IoT) over an insecure channel is vulnerable to several threats and needs proper attention to be secured from adversaries. Taking medication safety into consideration, this paper presents a secure authentication protocol for wireless medical sensor networks. The XOR scheme-based algorithm is applied to achieve the purposes of data confidentiality. The proposed architecture is realized as hardware in a field-programmable gate array (FPGA) device which acts as a secure edge computing device. The performance of the proposed protocol is evaluated and simulated via Verilog hardware description language. The functionality of the proposed protocol is verified using the Altera Quartus II software tool and implemented in the Altera Cyclone II DE2-70 FPGA development module. Furthermore, the output signals from the FPGA are measured in the 16702A logic analyzer system to demonstrate real-time functional verification.
Performance Modeling of a Pyrotechnically Actuated Pin Puller

An analytical model was developed to understand the physics and predict the functional performance of a pin puller. The formulated model is based on one-dimensional gas dynamics for an ideal gas. Resistive forces against pin shaft movement were measured in quasi-static mechanical tests, the results of which were incorporated into the model. The expansion chamber pressure and the pin shaft displacement were measured from an actual firing test and compared to the model prediction. The gas generation rate was adjusted by a correction factor, and the heat transfer rate was obtained through parametric analysis. The validity of the model is assessed for additional firing tests with different amounts of pyrotechnic charge. This model can provide knowledge on how the pin puller functions, and on which design parameters contribute the most to the actuation of the pin puller. Using this model, we estimate the functional safety factor by comparing the energy generated by the pyrotechnic charge to the energy required to accomplish the function.

The Anticipated Effect of Glycogen Synthase kinase 3 (GSK3) Antagonist on Pulp Tissue Repair in Rabbits

Purpose: To investigate the effect of Glycogen Synthase Kinase-3 (GSK3) antagonist on pulp tissue repair in rabbits. Materials and Methods: 24 adult healthy male rabbits were used in this study divided into three main groups: Group I (control): 2 rabbits with normal teeth without pulp exposure. Group II (TG): The exposed pulps of right posterior teeth of 22 rabbits were capped with KolSpon in association with 34 nM Tideglusib. Group III (MTA): The exposed pulps of left posterior teeth of 22 rabbits were capped with Mineral Trioxide Aggregate (MTA). The 2 rabbits with normal teeth and 6 rabbits with pulp capped posterior teeth were euthanized after one day. Their DNAs were extracted and tested for expression of Axin2 and β-actin by qPCR. 8 rabbits were euthanized after 4 weeks, and another 8 was euthanized after 6 weeks. The teeth were collected and prepared for immunohistochemical study using antiβ-catenin antibody. Results: The qPCR results showed the higher expression of Axin2 in the Tideglusib group than control group (without treatment) by about 5 folds and about 1.5 fold in the MTA group. The immunohistochemical results revealed the increase intensity in the Tideglusib group than MTA at four weeks with no significance difference (p>0.05). Whilst after 6 weeks the higher expression was in Tideglusib group with significance difference (p<0.05). Conclusion: The Tideglusib drug stimulates the expression of Axin2 transcription factor gene which is known to play a key role in regulation of odontoblast and osteoblast differentiation.

Guided-wave planar optical interconnects using highly multiplexed polymer waveguide holograms

An intraplanar interconnection scheme using substrate guided modes in conjunction with a highly multiplexed waveguide volume hologram is proposed. Acoustooptically addressed 1-to-50 passive and 1-to-2-to-100 reconfigurable interconnections with a fan-out diffraction efficiency of 55% at 514-nm wavelength are demonstrated. A coordinate transformation converts the 3-D diffraction problem into a 2-D one, which significantly simplifies the theoretical calculation. Intraplane massive fan-out optical interconnection using substrate guided mode provides both collinear and coplanar fan-out capability for data and clock signals. Colinearity of signal distribution allows the 2-D input signal array to be processes. The laminated waveguide device containing a highly multiplexed dichromated gelatin (DCG) hologram has been evaluated. >
Detecting attacks on IoT devices with probabilistic Bayesian neural networks and hunger games search optimization approaches

Technologies that enable physical objects to communicate with each other are attracting a lot of interest day by day. Internet of Things (IoT) is a communication network that is used to connect with technological devices and systems. The growth of IoT networks has led to malicious targeting of these systems by third parties. To prevent such malicious purposes, network security should be at the forefront. Recently, artificial intelligence‐based approaches have been used in security domains. Two accessible datasets were used in this study. The datasets consist of simulated bot IoT network traffic data containing distributed denial‐of‐service (DDoS) attack types. In the proposed approach, probabilistic Bayesian neural networks and normal Bayesian neural networks are used as the deep learning models. All features of the dataset were trained using two models. Then, the datasets were optimized using hunger games search (HGS) method and the most efficient parameters of the datasets were selected and retrained using deep learning models. In the analysis performed using the proposed approach, an overall accuracy of 100% was obtained for the dataset used in the first experiment and 99.99% for the dataset used in the second experiment. It was also observed that metaheuristic optimization helps the proposed approach to save time in detecting DDoS attacks.
Global information systems: factors or fiction

Summary form only given. The development and implementation of global information systems are uniquely and significantly impacted by a wide range of technical factors: an organization's information technology (IT) infrastructure, the quality and viability of existing systems, the technology currently being used, overall technical skills, and spending levels for all aspects of IT. They also are impacted by an equally wide range of nontechnical factors: the company's organizational structure; overall market forces; corporate, regional and local information requirements; cross-cultural issues; and national regulations impacting the implementation of information systems. When planning for the development and implementation of global information systems companies should develop a strategic information systems plan. The plan should include an evaluation of the company's current IT activities, and how they support its business strategies. A commitment by senior management of its support for the systems activities is critical to the success of any plan for new and/or improved information systems. A major enterprise in the entertainment business, a record company with operations world-wide, underwent such a study. It identified deficiencies in its current information systems and the impact of those deficiencies on its world-wide competitive position, and developed a strategic plan for improving its IT capabilities. This paper describes both factors impacting the development and implementation of global information systems, and the company's experiences relating to such systems.
Coloring of Bi4Ge3O12 – Mn crystals induced by electric field

The effect of the direct electric field on the optical transmittance of Bi4Ge3O12 single crystals doped with Mn is studied in the mode of using asymmetric contacts when only one electrode (Ag or In-Ga) is injected. It is found that changes in the optical transmittance spectra under the action of unipolar injection of electrons and holes are different. They also differ from the case of using symmetrical electrodes (double injection mode). The optimal temperature and field conditions for electrochromic coloring are determined from the correspondence between the manifestations of the electrochromic effect in Bi4Ge3O12 ─ Mn crystals and the current-voltage characteristics. It is shown that the maximum effect is achieved by injecting holes into a Bi4Ge3O12 ─ Mn sample annealed in a reducing atmosphere.

Harmonic load flow study for electric vehicle chargers

The electric vehicle (EV) is one of the ways of reducing air pollution in urban areas. Encouraging the charging of EVs at night will improve the loading factor of power systems. EV batteries can also be regarded as an energy reservoir of surplus energy without extra investment. However, harmonic current drawn by EV chargers may have impacts on the equipment of the power system. This paper is a case study of harmonic load flow of currents drawn by a group of EV chargers. The aim is to describe the study approach and to determine the level of impact of the harmonics generated.
Producing Electrical Energy by using wastage wind energy from exhaust fans of industries

Crisis of an electric power is a common phenomenon in a developing country. Day by day it’s become serious issue due to various factors, such as increasing demand, lower production capacity and transmission losses, etc. As a developing country, Many Industries are running on in our surroundings & also so many are being installed every day. We can see so many exhaust fans are being used to keep the working environment at a moderate temperature of an industry. These fans circulate air from inside to outside. From outside we can consider it as a high velocity wind source. In this Paper, we will show a process to use this wastage energy source. In this process, wind from all exhaust fans will be collected and driven through a single tunnel which will give a huge wind flow to the wind turbine. And then wind turbine will convert it into effective electrical energy. We will measure the velocity by using anemometer. This paper also consists of analyzed data of the wind velocity of the different industries of Bangladesh. We also analyze these produced electricity are whether profitable or not from the existing system. Thus we can utilize the wastage wind energy from the exhaust fans of the industries and producing electrical energy we can reduce the load of national grid.
Users as Co-Inventors: A Model for Involving Users in the Early Stages of New Product Development

Abstract Despite the increasing importance attributed to the involvement of users in the early stages of the new product development process, there have been only limited attempts that comprehensively detail how the user involvement approach is implemented in practice. This knowledge deficit is having consequential effects on user involvement, making its successful implication difficult to achieve as user involvement is heavily dependent on how the involvement process is managed (Magnusson et al., 2003). This study aims to close this knowledge gap by presenting a managerial framework for maximising user involvement in predevelopment activities and in so doing, will obtain implementable guidelines that can be used by organisations to enhance the delivery of innovative and appealing new product concepts. The existing literature on user involvement and relationship marketing were utilised as a starting point to develop an integrated framework. In addition to this, data was gathered from a longitudinal study. Due to the nature of the research, that is, the need to understand a real-life phenomenon in depth, as well as the fact that relatively little knowledge is available on the research topic, it was deemed appropriate to merge aspects from action research with a single interpretive case study approach. This allowed the researcher to become actively involved with the phenomenon under research, hence, facilitating the gathering of a comprehensive collection of qualitative data on the actual interactions that occurred between the manufacturer and user. The key findings of this research illustrated the importance of managing the complex relational dynamics inherent in a close collaborative manufacturer-user relationship. In addition, the findings clearly indicated that the involvement of users does not occur in a vacuum. Rather, the success of the collaboration is influenced by a number of enabling factors, which combine to influence the ways in which the manufacturer and user structure and manage their interactions. The findings further indicate that the benefits of such collaborations may only be enjoyed when the process is managed in an effective and efficient manner, thus the presence of an individual capable of coordinating the process is essential. The thesis concluded with the development of an “integrated framework‟ for managing user involvement at the early stages of the new product development process.
Enabling SMEs to take full advantage of e-business

Electronic business is rapidly changing the relationships between supply chain partners. This paper looks at what is needed to allow SMEs to participate fully in supply chain integration. First, current trends in supply chain integration, electronic commerce, and Internet support are examined. Next, the goals and results of a study are presented which addressed SME needs in fast moving consumer goods supply chains. These concepts are then integrated to determine a way forward for SMEs to participate in e-business. It is found that current Virtual Markets (web-sites or on-line communities that facilitate finding a buyer or seller and track orders) address some customer - supplier relationships but need many enhancements before they can support fully integrated supply chains.
