Commissioning and System Integration Tests for an Industrial Manipulator Workstation

Industrial systems are composed of several sub systems and architectures that are provided by different manufacturers. System integration aims at enabling a developer to combine these unit systems with limited functionality into one system that can accomplish the execution of required process. Modern integrated systems are developed on top of service-oriented architecture and use webservices for information exchange. Such systems are swiftly deployable and ensure platform interoperability, system adaptability and service reusability. Meanwhile, system integration tests help to reduce the complexity during the integration phase thus ensuring process uniformity. This thesis focuses on deploying a robotic manipulator in an industrial cell. The robot is in-stalled in the assembly line as service provider while services are invoked by using RESTful web services. Second objective of the thesis is to implement a free shape path planning algorithm for the deployed autonomous manipulator to follow the desired curve. The last component of this thesis is focused on developing integration tests to examine and verify the designed system. The robot was commissioned at the FASTory assembly line, installed at FAST lab of Tampere University. The free shape paths were implemented by interpolating Bezier curves using De Casteljau algorithm. System was successfully integrated and verified using Top-down depth first and bottom-up breadth first integration testing approaches

Cross-Site Request Forgery Attacks and Preventions

CSRF stands for Cross-Site Request Forgery, which is among the top web vulnerabilities in which the attacker maliciously exploits a website using victims’ credentials and sends unauthorized actions/calls on a trusted web application. In Cross-site request forgery, the attacker sends a malicious forged link to the user. Upon clicking, the forged request is sent on behalf of the user which results in data leakage. Till today, numerous defense mechanisms (on both the client and server sides) have been proposed as the result of increasing attacks and leakage of personal data. Such mechanisms include HTTP header, validation of random tokens, hybrid-model HTTP and content analysis, client-server proxy, and so on. However, even today, such attacks exist and occur. This report analyzes various existing defense mechanisms and models, critically assesses each of them, and addresses the voids in each of them. It also describes how combining two mechanisms help overcome the flaws

Prediction of Rutting in Flexible Pavements using Finite Element Method

In this research study three dimensional (3D) finite element analysis are performed on a flexible pavement section for different material properties, temperature and loading conditions. The main objective of this study is to predict the rut depth under different conditions of temperature, loadings and material properties. Three dimensional finite element model of flexible pavement is developed using ABAQUS to predict rut depth. The pavement system is assumed to be an elastic multi-layers system with each layer being isotropic, homogeneous with specified Resilient Modulus (Mr) and Poisson ratio (µ). With the exception of the bottom subgrade layer, each layer is extending to an unlimited horizontal extent and has a finite thickness. The pavement system analyze in this study for a cyclic load of 10000 cycles taken as 0.01sec per cycle. Standard Axle Load (ESAL) of 18 kips (80 kN) loading on an axle with a dual set of tires, the wheel spacing is 13.78 in (350 mm) with a tire contact pressure of 100 psi (0.69 MPa) is used. After performing a series of analysis the results showed that rut depth increases with increase in temperature and loading and decreases by using base stabilizer. Doi: 10.28991/cej-2021-03091727 Full Text: PD

Resume Ranking Using Natural Language Processing

Finding the ideal candidate for a position is one of a company’s most important and crucial tasks. The conventional approaches typically necessitate spending a significant amount of time manually going through each applicant’s application, reviewing their resumes, and compiling a shortlist of candidates who ought to be contacted for an interview. Numerous resumes are received by companies, many of which are poorly formatted. On the other hand, selecting a candidate based on their resume has not yet been completely automated. The applicant will be able to upload their pdf resume on our website. We will use Natural Language Processing to rank abilities and work insight from the unstructured resumes. Our model will rank the best candidate in each category. The process of screening is made easier by the removal of all irrelevant information, and recruiters are able to better analyze each resume in less time

File Sharing & Copyright Infringement in Peer-to-Peer

In the past, we used a centralized system which is server-client architecture but today along with server-client peer-to-peer or P2P is widely used which is based on the decentralized system in it each client is also a server purpose of the server for all the different clients as well by analyzing various articles, research papers, and literary works. We investigate many software and technological innovations including Napster, uTorrent, BitTorrent, and Gnutella.Peer-to-peer technology might go either way in the future; perhaps the copyright legislation has made it better or worse. Peer-to-peer has an impact on the music and film industries, among others, since it makes it simple for users to distribute information that is protected by copyright. Additionally, this article considers copyright infringement from both domestic and foreign viewpoints. The article demonstrates the connection between peer-to-peer file sharing and copyright infringement in general as well as the difficulties in safeguarding owners' copyrights on a P2P network. People mistakenly assume that it is impossible to identify and track copyright violations, yet some tools and procedures may be used to identify material that is protected by copyrights

Characteristics of traumatic out-of-hospital cardiac arrest patients presenting to major centers in Karachi, Pakistan-A longitudinal cohort study

Background: Trauma is the leading cause of death for adults under 44 years of age. Survival after traumatic out-of-hospital cardiac arrest (OHCA) has been reported to be poor, and its epidemiology is not well defined. A few studies have reported better survival in response to pre-hospital life-saving interventions. Currently, no published data on traumatic cardiac arrests in the field exist from low- and lower middle-income countries. We aimed to explore the epidemiology and outcomes of traumatic OHCA patients from Karachi, Pakistan. We conducted a longitudinal cohort study at emergency departments (ED) of five major public and private hospitals of the city from January to April 2013. Data was collected on all adult patients (age 18 years or more) presenting to the hospitals directly from field with cardiac arrest and history of trauma using a structured questionnaire. Patients with do-not-resuscitate status and those referred from other hospitals were excluded.Results: During 3 months, a total of 187 patients were enrolled with mean age of 35.1 years. About 95% were men, and 68.4% had a penetrating injury. Even though half of the patients had a witnessed arrest, none received a bystander cardiopulmonary resuscitation (CPR). 83.4% were brought to the hospital in an ambulance, with median response and scene times of 3 and 2 min respectively; however, only 3 received any pre-hospital life-support interventions. One hundred eighty-one patients (96.7%) were pronounced dead on arrival to the ED, and of the remaining 6 patients, 4 received CPR in the EDs. Overall survival at the end of ED stay was 0%. Patients who received life-support interventions survived for longer time, though not clinically significant, as compared to those who did not (45 min vs. 35 min, p = 0.02).Conclusion: There was no survival after a traumatic OHCA in Karachi, Pakistan. Even though ambulances reached the scene in a very short time, pre-hospital interventions were largely absent. There is a strong need to strengthen our pre-hospital care system but most importantly train the general public to deal with emergencies and be able to provide timely bystander CPR

Volatility Linkages between Equity Markets of Pakistan, India, Singapore and Hong Kong: A GARCH BEKK Approach

The purpose of current study is to explore the volatility linkages between four Asian equity markets, which arePakistan (Karachi Stock Exchange), India (Bombay Stock Exchange), Hong Kong (Hang Sang Index) and Singapore (Strait Time Index). We estimate Multivariate GARCH BEKK model using weekly returns from January 2000 to August 2011.Direct evidences of linkages are found among all markets with respect to conditional mean returns and volatility.Own volatility spillover is found greater than cross volatility spillover in all emerging and developed economies.The insinuation of this study is that overseas investors may take advantage from the decrease of uncertainty by accumulating the stocks in the emerging markets to their investment portfolio

Accuracy of diagnosis and relationship with quality of emergency medicine training program

An indicator for emergency room performance is the ability to establish the correct diagnosis within the emergency room over the years. The authors chose to examine the non-congruence of Emergency Room diagnoses to that established after hospital stay for three selected years. A total of 8488 records were reviewed and all disparate diagnosis were recorded and categorized. Retrospective chart reviews were done from July 2008 to February 2009 at the Aga Khan University Hospital, Karachi. A substantial reduction in the percentage of disparate diagnoses was seen over the years from 41% in the initial year to 14% in the last year evaluated. It was concluded that over the years there has been an improvement in the reliability of Emergency Room diagnoses at the Aga Khan University Hospital, Karachi
