Common Problems of Airport Passenger Terminal Operations

Airport passenger terminal operations include all the activities that passengers will experience in the airport from being processed through boarding to the plane and the other services available at the terminal facility. The consistent increases in passenger rates have had major effects on these procedures among the world’s airports and have caused certain problems for airport terminal operations. This paper provides a brief introduction about airport passenger terminals and their operations and identifies several frequently observed problems that exist among the airports. In addition to identifying the outcomes that have resulted from each of these problems, many suggestions or recommended solutions have been provided. These recommendations are based on research and studies available in the literature. Relevant sources that have been used in the literature include books, journal articles, official aviation or airport related reports, and online news articles

The Perception of Chinese Construction Professionals Towards the Obstacles Implementing Green Construction

Green construction plays a key role as building block of sustainable development. The economy is significantly affected by the construction industry of the country. There are certain stakeholders in the green construction industry, however project managers (PMs) play significant role in the process of a construction/ rehabilitation project. Generally, the initiative for change or implementing a new system is very challenging issue to deal with. Project manager has to encounter certain obstacles either at several stages of the green construction projects. The present study deals with the identification of the most critical obstacles that have the greatest influence on a project’s outcome in general and particularly in China. To rank the different obstacles extracted from the literature, we use multi criteria decision making (MCDM) tool i.e. TOPSIS. For obtaining input data a team of six experts (project managers) from top Chinese construction companies with an experience of more than 12 years were selected. The results depicts that the most relevant and important obstacles which are critical for green project management are managerial and psychological obstacles and they need to be addressed to improve the project management performance. Keywords: green construction, project management, topsis, project managers

Colloquialising modern standard Arabic text for improved speech recognition

Modern standard Arabic (MSA) is the official language of spoken and written Arabic media. Colloquial Arabic (CA) is the set of spoken variants of modern Arabic that exist in the form of regional dialects. CA is used in informal and everyday conversations while MSA is formal communication. An Arabic speaker switches between the two variants according to the situation. Developing an automatic speech recognition system always requires a large collection of transcribed speech or text, and for CA dialects this is an issue. CA has limited textual resources because it exists only as a spoken language, without a standardised written form unlike MSA. This paper focuses on the data sparsity issue in CA textual resources and proposes a strategy to emulate a native speaker in colloquialising MSA to be used in CA language models (LMs) by use of a machine translation (MT) framework. The empirical results in Levantine CA show that using LMs estimated from colloquialised MSA data outperformed MSA LMs with a perplexity reduction up to 68% relative. In addition, interpolating colloquialised MSA LMs with a CA LMs improved speech recognition performance by 4% relative

Effect of porosity on unsteady MHD convection flow Past a moving vertical plate with ramped wall temperature

The unsteady MHD convective flow of an electrically conducting fluid embedded in a porous medium along moving infinite vertical plate with ramped wall temperature and radiation in a rotating system is investigated here. The fluid taken is incompressible and viscous. The governing PDE’s of the model are solved by using integral transform method. The analytical solutions for the velocity, concentration and temperature are obtained. The expressions for skin friction, rate of mass transfer and heat transfer near the plate are obtained. The effects of various parameters like porosity of the medium, magnetic field, Soret number, thermal radiation, rotation, radiation and Hall current on the flow field are discussed. It is observed that velocity increases with the increase in the porosity parameter K. It reveals that a porous medium having large permeability supports the movement of the fluid in the system. Also, it is noticed that Hall parameter reduces the resistive effect of the applied magnetic field. Such a study assumes importance because both rotation and Hall current induce secondary flow in the flow-field. The results of the research may be useful in many industrial applications

Study of Soret and Ion slip effects on MHD flow near an Oscillating Vertical Plate in a Rotating System

This study analyses the Soret, Hall and ion slip effects on a free convective flow of an electrically conducting, incompressible and viscous fluid near the vertical oscillatory infinite plate in a rotating system. A set of dimensionless governing equations of the model is obtained. As the equations are linear, an exact solution can be obtained by using Laplace transform method. The influence of various parameters on the concentration, temperature, velocity, Sherwood number and Nusselt number are discussed with the help of graphs. The numerical values of skin-friction are shown in tables. Applications of the study arise in field like planetary and solar plasma fluid dynamical systems, magnetic field controlled materials processing systems, rotating MHD induction machine energy generators etc

Statcom Simulation Search Based On Cascaded Multilevel Transformer

Future strategic maneuvers are mission critical within the rigidity and safety intensity framework, and therefore the Responsive Force Rewards tool has an exceptionally wide range within the force action framework. In recent times, innovation in density tools, in particular the Current Adaptive Transfer Framework (FACTS) has undergone a rapid change of course. The DC transmission voltage is an important factor in the static activity of devices. In this document, a different flat control strategy is used to achieve parity in the DC transmission voltage, and includes the DC transmission voltage by large control and individual control per unit cycle. Finally, the reproducibility results for 20-kV, 2-MVA CMC-STATCOM confirm the validity and integrity of the control system and regulation strategy in this document using PSCAD / EMTDC

An unusual presentation of visual hallucinations with zolpidem: a case report

Zolpidem is a hypnotic drug with rapid -onset and short duration of action. It is popularly used for the induction and maintenance of sleep in adults suffering from insomnia. It supersedes benzodiazepines with better tolerability and has fewer side effects such as less residual sedation and the potential for rebound insomnia and dependence is also less. Adverse neuropsychiatric reactions such as visual hallucinations, amnesia, sleepwalking and nocturnal eating are known to occur with zolpidem. Literature suggests higher incidence of visual hallucinations with zolpidem when used along with selective serotonin reuptake inhibitors. Furthermore, visual hallucinations are one of the causes for drug withdrawal. We are reporting a case of zolpidem induced visual hallucinations when used alone and also which disappeared with proper assurance to the patient in subsequent use

A Novel Approach for Arabic Text Steganography Based on the "BloodGroup" Text Hiding Method

Steganography is the science of hiding certain messages (data) in groups of irrelevant data possibly of other form. The purpose of steganography is covert communication to hide the existence of a message from an intermediary. Text Steganography is the process of embedding secret message (text) in another text (cover text) so that the existence of secret message cannot be detected by a third party. This paper presents a novel approach for text steganography using the Blood Group (BG) method based on the behavior of blood group. Experimentally it is found that the proposed method got good results in capacity, hiding capacity, time complexity, robustness, visibility, and similarity which shows its superiority as compared to most several existing methods

PROTON PUMP INHIBITORS AND THE RISK OF CHRONIC KIDNEY DISEASES: A CRITICAL REVIEW

Proton pump inhibitors (PPIs) are most widely used medications for acid related gastrointestinal disorders. Accessible evidence based studies suggest that the increased use of PPI is linked to a greater risk of developing kidney diseases. This review aims to determine the association of kidney disease with the use of proton pump inhibitor with various study designs. PubMed, Scopus and Google Scholar databases as well as a reference list of relevant articles were systematically searched for studies by using the following search terms; ‘proton pump inhibitors’, ‘acute kidney injury’, ‘chronic kidney disease’ and ‘end stage renal disease’. Both observational and randomized controlled trials (RCTs) exploring the association of PPI use with kidney disease were eligible for inclusion. A total of 8 articles, including 9 studies (n = 794,349 participants) were identified and included in the review. Majority of the studies showed a higher risk of kidney outcomes in patients taking PPIs, with effect higher of acute kidney injury (4-to 6-fold) compared with chronic kidney disease and end stage renal disease (1.5-to 2.5-fold). However, the studies suggest that the strength of evidence is weak and could not prove causation. The risk increased considerably with the use of high dose of PPIs and prolonged duration of exposure necessitates the monitoring of renal function. Exercising vigilance in PPI use and cessation of proton pump inhibitor when there is no clear indication may be a reasonable approach to reduce the population burden of kidney diseases
