Empirical validation of software metrics suites to predict fault proneness in object-oriented (OO) components is essential ensure their practical use industrial settings. In this paper, we empirically validate three OO for ability quality terms fault-proneness: the Chidamber and Kemerer (CK) metrics, Abreu's Metrics Object-Oriented Design (MOOD), Bansiya Davis' Quality (QMOOD). Some CK class have previously been shown be good predictors initial quality. However, other two not heavily...

A key advantage of social media is the real-time exchange views with large communities. In disaster situations, such bidirectional information most useful to victims and support teams, especially in communications authorities, volunteers, public. This paper addresses challenges faced by healthcare supply chain during COVID-19 pandemic analyses Twitter data using an Artificial Intelligence-driven multi-step approach. We investigate tweets for about chains, as scarcity testing kits, oxygen...

Purpose Few companies have had the success that Toyota Motor Corporation has experienced over past 70 years. Many give credit for Toyota's to company's famous Production System. Companies outside of tried implement versions system as Lean production; however, few Toyota, and none sustained success. In 2001, released a publication entitled The Way 2001 set globalized standards culture drives Design/methodology/approach This research examines effect on implementation production Toyota. A...

:This article reviews project management education, from graduate and certificate programs to organizational programs. It includes survey results of current practitioners with regard training. has been found that there are both cover the recommended knowledge areas. Less than half organizations in had any type training program 41% managers felt their prepared them for role. From those who trained, 73% Recommendations provided employees, employers, academia help bridge gap between skills...

An approach using semantic metrics to provide insight into software quality early in the design phase of development by automatically analysing natural language (NL) specifications for object-oriented systems is presented. Semantic are based on meaning within problem domain. In this paper, we extend analyse specifications. Since can now be calculated from through maintenance, they a consistent and seamless type metric that collected entire lifecycle. We discuss our semMet system, an NL-based...

The objective of this report is to present a simplified, activity-based costing approach for hospital emergency departments (EDs) use with Lean Six Sigma cost-benefit analyses. cost model complexity reduced by removing diagnostic and condition-specific costs, thereby revealing the underlying process activities' inefficiencies. Examples are provided evaluating savings from reducing discharge delays impact keeping patients in ED (boarding) after decision admit has been made....

Abstract This paper presents a new semantically‐based metric for object‐oriented systems, called the Semantic Class Definition Entropy (SCDE) metric, which examines implementation domain content of class to measure complexity. The is determined using knowledge‐based program understanding system. metric's examination provides more direct mapping between and common human complexity analysis than possible with traditional measures based on syntactic aspects (software related format code)....

Forecasting traffic volumes to support infrastructure decisions is the heart of travel demand modeling process. The most commonly used methodology for obtaining these forecasted four-step process that considers generation, distribution, mode choice, and route assignment trips. Each step performed independently, almost always through use computer software, achieve final volumes. This paper examines possibility forecasting by using a multiple linear regression model perform what termed direct...

There is a demand for more STEM professionals. Early elementary students’ conceptions about engineering can influence whether or not they explore career paths and ultimately select an career. This study examined the students have regarding work that engineers perform. The research questions were following: (1) what images do early associate with engineers, (2) these associations vary from grade to grade, (3) are there gendered differences in associations, (4) how this sample compare broader...

Search and Rescue Operations (SRO) are notoriously difficult as they typically involve human operations in high risk low visibility environments. Often, stakeholders only have a general perception of the possible adversities situational environment. Ultimately, success these is function manpower available, terrain region, informed-decision-making based on mapping objective completion search rescue tasks with lower casualties. A practical solution to this problem leverage use autonomous...

This paper examines a new methodology to predict external trip exchanges in small urban communities. The documents study performed on several communities Alabama and includes video surveillance data collection methodology, analysis, model development, test versus existing models. presented this is shown provide more accurate results when compared models demonstrated transferability similar city.

Software practitioners need ways to assess their software, and metrics can provide an automated way do that, providing valuable feedback with little effort earlier than the testing phase. Semantic were proposed quantify aspects of software quality based on meaning software's task in domain. Unlike traditional metrics, semantic not rely code syntax. Instead, are calculated from domain information, using knowledge base a program understanding system. Because syntax, they be before is fully...

The vision for space includes Shuttle retirement by 2010 and development of new launch vehicles; however, budget increases are not projected. To control costs additional insight into cost factors early in the system life cycle is needed. This article reports on a vehicle upper-stage engine trade study where was gained using net present value applying set risk to incorporate risks inherent key phases. A matrix presented that provides general framework assessing these levels. approach shows...

The team communication dynamics is one of the crucial factors that can provide a plethora information regarding evolution situational awareness and in turn highlight pivotal moments for mission success any combat training simulation scenario. Specifically, this work, we study data collected from firefighting simulation. large volume between individual members recorded throughout provides an ideal basis use Big Data analytics sentiment analysis to derive deeper insights on various levels...

Leadership within an organization is crucial to its performance, growth, and future success in the industry. While existing literature explores impact of leadership on organizational there remains a notable gap research specifically addressing systems trends organizations awarded Baldrige Performance Excellence award. To better understand whether themes exist high-performing leadership, applications (N = 9) from award winning were analyzed using deductive content analysis identify thematic...

Human interactions with Artificial Intelligence (AI) have become a ubiquitous phenomenon in our society. It plays major role defense and espionage the context of AI-based autonomous systems such as drones ground robots that are sent to front lines navigate terrains, map surroundings, identify adversaries environment. In these types scenarios, hostages may be spread out over larger geographical area. Reliance on vision alone not only obscured insufficient but also can expose soldiers or human...
