This research explores the collective impact of overtime, random breakdown, discontinuous issuing rule, and scrap on batch production planning in a supply-chain environment. In today’s global business environment, manufacturing firms encounter numerous operational challenges. Externally, they must promptly satisfy the customers’ various requests, while internally, they must cautiously manage several inevitable issues in the fabrication process. These issues might be concerned with scrap, random breakdown, etc. Resolving such issues is crucial for meeting the due dates of customers’ orders, adhering to the expected manufacturing schedules, product quality, and minimizing the total fabrication-transportation-inventory costs. The study develops a model to characterize …

Gnss Cycle Slip Detection And Estimation Using Lstm-Based Autoencoder Model., Ahmed Ragheb, Ahmed Zekry, Mohamed Elhabiby

Mansoura Engineering Journal

Global Navigation Satellite Systems (GNSSs) are used in many navigation and positioning applications. Unfortunately, a GNSS signal may suffer from some errors, such as cycle slips, which deteriorate the positioning solution. A cycle slip is defined as a sudden jump by an integer number of cycles in the GNSS carrier phase observations. Signal blockage or/and high troposphere activities are the most common causes for GNSSs’ cycle slips. Therefore, cycle slips should be detected and corrected to determine reliable positioning estimations. A new approach for cycle slip detection and repair is proposed based on a master-rover phase-difference with a deep Long …

Assessment Of Non-Saccharomyces Yeast Species As Secondary Fermenters In Beer, Paul J. Clark

Master of Science in Integrative Biology Theses

Secondary fermentation of beer is traditionally used to condition and refine the sensory profile of a beer. During methods such as barrel aging or lagering, the yeast continues to produce flavor-active compounds. Some methods include the intentional inoculation of microorganisms or the utilization of natural consortia associated with a barrel, fruit, or additive for the generation of desired sensory profiles. As unique products increase in popularity, brewers have begun to experiment with secondary fermentation using alternative yeast species as bioflavorants. To assess the viability of an organism’s application to brewing, the physiochemical properties of beer and their impact on the …

Simulation For A Mems-Based Ctrnn Ultra-Low Power Implementation Of Human Activity Recognition, Muhammad Emad-Ud-Din, Mohammad H. Hasan, Roozbeh Jafari, Siavash Pourkamali, Fadi M. Alsaleem

Durham School of Architectural Engineering and Construction: Faculty Publications

This paper presents an energy-efficient classification framework that performs human activity recognition (HAR). Typically, HAR classification tasks require a computational platform that includes a processor and memory along with sensors and their interfaces, all of which consume significant power. The presented framework employs microelectromechanical systems (MEMS) based Continuous Time Recurrent Neural Network (CTRNN) to performHAR tasks very efficiently. In a real physical implementation, we show that the MEMS-CTRNN nodes can perform computing while consuming power on a nano-watts scale compared to the micro-watts state-of-the-art hardware. We also confirm that this huge power reduction doesn’t come at the expense of reduced …

Emr: A New Metric To Assess The Resilience Of Directional Mmwave Channels To Blockages, Faith Erden, Ozgur Ozdemir, Ismail Guvenc, David W. Matolak

Faculty Publications

Millimeter-wave (mmWave) communication systems require narrow beams to compensate for high path loss and to increase the communication range. If an obstacle blocks the dominant communication direction, alternative paths (directions) should be quickly identified to maintain reliable connectivity. In this paper, we introduce a new metric to quantify the Effective Multipath Richness (EMR) of a directional communication channel in the angular domain. In particular, the proposed metric takes into account the strength and spatial diversity of the resolved Multipath Components (MPCs), while also considering the beamwidth of the communication link and the blockage characteristics. The metric is defined as a …

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Tea (Camellia sinensis) has been found as an important medicinal beverage for human which is consumed all over the world. Primarily, the majority of tea is being cultivated in Asia and Africa, however it is commercially produced by more than 60 countries. Though substantial amount is produced, its processing system is still underdeveloped which leads to decrease in export opportunity as well as low monetary value. Moreover, the traditional method of tea grading and sorting is laborious, inefficient, and costly which ultimately produces the low-quality heterogeneous products. Processing and grading of tea granules after drying is very important …

Optimal Placement Of Fuses And Switches In Active Distribution Networks Using Value-Based Minlp, N. Gholizadeh, S.H. Hosseinian, M. Abedi, Hamed Nafisi, P. Siano

Articles

Contingency conditions in distribution networks create financial losses for different parts of the system including electricity customers, electricity retailers, distributed generation (DG) units, etc. Therefore, protective device allocation methods have been introduced in recent years to enhance the reliability of the power system. In this study, a new formulation is proposed to find the optimal places of sectionalizing switches and fuses while taking the financial loss of both electricity customers and DG units into account. The current method has the flexibility to consider DG effect on any location of the network and its islanded operation in case of contingencies. Moreover, …

Khamis, Fidelis Levi Ombura, Chrysantus M. Tanga, Komi K.M. Fiaboe, Sevgan Subramanian, Sunday Ekesi, Oliver K. Schlüter, Arnold Van Huis, Christian Borgemeister

All Peer-Reviewed Publications

Globally, the expansion of livestock and fisheries production is severely constrained due to the increasing costs and ecological footprint of feed constituents. The utilization of black soldier fly (BSF) as an alternative protein ingredient to fishmeal and soybean in animal feed has been widely documented. The black soldier fly larvae (BSFL) used are known to voraciously feed and grow in contaminated organic wastes. Thus, several concerns about their safety for inclusion into animal feed remain largely unaddressed. This study evaluated both culture-dependent sequence-based and 16S rDNA amplification analysis to isolate and identify bacterial species associated with BSFL fed on chicken …

Usdla: An Instructional Media Selection Guide For Distance Learning, Jolly T. Holden, Philip Westfall

Online Journal of Space Communication

Purpose and Use of the Media Selection Guide

Increasingly, educators and trainers are challenged within their respective
organizations to provide for the efficient distribution of instructional con-
tent using instructional media. The appropriate selection of instructional
media to support distance learning is not intuitive and does not occur as a
matter of personal preference. On the contrary, instructional media selec-
tion is a systematic sequence of qualitative processes based on sound in-
structional design principles. Although media selection is often mentioned
when studying the discipline of instructional technology or Instructional
Systems Design (ISD), it is sometimes overlooked when applying the …

Kyrgyzstan is a landlocked country in Central Asia, one of the former Soviet Union republics, endowed with few natural resources, but it has a tremendously advantageous location on the major crossroads between Asia and Europe. Under the Soviet system the educational level of the population used to be very high in Kyrgyzstan. Recently the quality of education has started to worsen due to the continuous migration of the nation's specialists to more economically developed countries.

Distance Education Via Satellite: An Early Case Study Of The Indonesian Distance Education Satellite System, Willard D. Shaw

Online Journal of Space Communication

In 1980, the U.S. Agency for International Development initiated the AID Rural Satellite Program (RSP) to explore the potential of telecommunications as a means of extending scarce expert resources and expanding educational opportunities to remote and rural areas. Building on simple, interactive, and inexpensive telephone-based technologies, the Program developed teleconferencing systems for use as a development tool. Three pilot projects-in Indonesia, the West Indies, and Peru-were implemented to test and demonstrate that audioteleconferencing could reliably and affordably support development activities in education, health and agriculture.

Satellite Technology Applications In Education: Examples From Greece, Yioryos Nardis

Online Journal of Space Communication

In ancient Greece, there was a mechanism for processing space information from the earth. The Antikythera has since been referred to as the world's first (mechanical) computer. In Greece, the Antikythera mechanism was used to fabricate calendars and schedules for seasons of harvesting and for organizing religious festivals. More than two millennia later, the descendants of these early scholars and technicians are still using outer space to educate themselves, but now the mechanism is electronic and digital using software and spaced-based satellites.

The Broadband Satellite System "Ipstar": Applications In Asia-Pacific Region, Masudul Biswas

Online Journal of Space Communication

The increasing trend of data traffic has turned the world into an information society. Even so, a significant portion of the areas and populations of the world have remained outside the flow of data traffic keeping them information-poor. That is why the issue of "digital divide" has popped up. But it is the cost-effectiveness factor of delivering systems that has guided the changes taking place in information and communication technologies that will ultimately benefit the end users.
