Comparative analysis of digital artifact persistence between file format

As we know digital forensics is a scientific examination and analysis of data that when it held on, or where it is retrieved from so that the information collected can be used as evidence in a court of law. Nowadays, digital evidence are very useful to provide when case in court. The deleted file of document, audio or image can be recover back as digital artifact [1]. Therefore, it is very clear from the experience that digital artifact are important witnesses to care

Archaeology and fertility cult in the Ancient Mediterranean

Includes Contents, Preface, List of members with addresses and Opening Addresses.The term "Fertility Cult" has been fashionable for the last three generations of anthropologists and archaeologists, and may at times have been used and abused too readily. Also, the term is very general and is open to personal evaluations and interpretations. The word cult implies beliefs and rituals or at least performances. When used, the term should be defined both in terms of concepts and of ritualistic behaviour involved.peer-reviewe

Study of burnt rice husk performance in reedbeds to remove pollutant form landfill leachate

In this study, the raw material used to treat the leachate is rice husks. Analyses were done on their physical and optical parameters to determine the removal and reduction of heavy metals (iron, chromium and nickel), BOD 5, COD, ammonia nitrogen, turbidity, colour and odour in leachate using biological treatment. For the physical, the testing was running to examine the performance of reedbed to improve landfill leachate. While for the optical parameter, scanning electron microscope (SEM) was used to investigate their morphological structures to determine the effect of burnt rice husk sizes and porosity on pollutant removal. At the end of the study, those criteria were exhibited from testing results, the treatment of leachate in reedbeds effective until four days and this reedbeds can be commercialized. Besides that, the raw materials used can be abundantly earned without cost, which in turn reduce the cost of production. Moreover, by this way, it can reduce the sludge disposal, which make it highly valuable in terms of environmental, and market value

Semantic Localization and Mapping in Robot Vision

Integration of human semantics plays an increasing role in robotics tasks such as mapping, localization and detection. Increased use of semantics serves multiple purposes, including giving computers the ability to process and present data containing human meaningful concepts, allowing computers to employ human reasoning to accomplish tasks. This dissertation presents three solutions which incorporate semantics onto visual data in order to address these problems. First, on the problem of constructing topological maps from sequence of images. The proposed solution includes a novel image similarity score which uses dynamic programming to match images using both appearance and relative positions of local features simultaneously. An MRF is constructed to model the probability of loop-closures and a locally optimal labeling is found using Loopy-BP. The recovered loop closures are then used to generate a topological map. Results are presented on four urban sequences and one indoor sequence. The second system uses video and annotated maps to solve localization. Data association is achieved through detection of object classes, annotated in prior maps, rather than through detection of visual features. To avoid the caveats of object recognition, a new representation of query images is introduced consisting of a vector of detection scores for each object class. Using soft object detections, hypotheses about pose are refined through particle filtering. Experiments include both small office spaces, and a large open urban rail station with semantically ambiguous places. This approach showcases a representation that is both robust and can exploit the plethora of existing prior maps for GPS-denied environments while avoiding the data association problems encountered when matching point clouds or visual features. Finally, a purely vision-based approach for constructing semantic maps given camera pose and simple object exemplar images. Object response heatmaps are combined with known pose to back-project detection information onto the world. These update the world model, integrating information over time as the camera moves. The approach avoids making hard decisions on object recognition, and aggregates evidence about objects in the world coordinate system. These solutions simultaneously showcase the contribution of semantics in robotics and provide state of the art solutions to these fundamental problems

Personal financing planning: the importance of saving early for retirement plan / Nur Anati Khairudin

Financial planning involves deciding what investments and activities would be most appropriate under both personal and broader economic circumstances. The purpose of this research is to identify the level of knowledge and employee’s awareness toward savings early for retirement. Therefore, from this research, it will help researcher to define and identifies the majority of population savings early for retirement. For the purpose of this study, the researcher has adopted the descriptive research design due to its used through survey method. The survey involved a structured questionnaire given to respondents and designed to elicit specific information. The population has been tested at Felcra Berhad Wilayah Tengah whereas its employees become the researcher’s respondent and 40 questionnaires were distributed among them. There are four types of analysis in SPSS program that had been used in the study to analyze the data frequency analysis, reliability testing, descriptive statistic and data correlations. From the findings, most of respondents agree that knowledge of financial planning is most important in creating awareness towards savings early for retirement. This study also finds out the most of respondents are disagree that savings some of income regularly is easy but most of respondent are agree that savings some of income regularly is important. Finally, the researcher can conclude that there is significant relationship for both of independent variables level of knowledge and employees’ awareness towards start savings early for retirement. Thus, researcher can make conclusion that both of independent variables have positive relationship with start saving early for retirement
