Smart Indoor Home Surveillance Monitoring System Using Raspberry Pi

Internet of Things (IoTs) are internet computing devices which are connected to everyday objects that can receive and transmit data intelligently. IoTs allow human to interact and control everyday objects wirelessly to provide more convenience in their lifestyle. The Raspberry Pi is a small, lightweight and cheap single board computer that can fit on human’s palm. Security plays a big role in a home. People concern about security by preventing any intruders to enter their home. This is to prevent loss of privacy and assets. The closed-circuit television (CCTV) is one of the device used to monitor the secured area for any intruders. The use of traditional CCTV to monitor the secured area have three limitations, which are requiring a huge volume of storage to store all the videos regardless there are intruders or not, does not notify the users immediately when there are motions detected, and users must always check the CCTV recorded videos regularly to identity any intruders. Therefore, a smart surveillance monitoring system is proposed to solve this problem by detecting intruders and capturing image of the intruder. Notifications will also be sent to the user immediately when motions are detected. This smart surveillance monitoring system only store the images of the intruders that triggered the motion sensor, making this system uses significantly less storage space. The proposed Raspberry Pi is connected with a passive infrared (PIR) motion sensor, a webcam and internet connection, the whole device can be configured to carry out the surveillance tasks. The objectives of this project are to design, implement and test the surveillance system using the Raspberry Pi. This proposed surveillance system provides the user with live stream of video feed for the user. Whenever a motion is detected by the PIR motion sensor, the web camera may capture an image of the intruder and alert the users (owners) through Short Message Service (SMS) and email notifications. The methodology used to develop this system is by using the object-oriented analysis and design (OOAD) model.
Wastewater treatment plants as a source of microbial pathogens in receiving watersheds

Wastewater treatment facilities have become sin quo non in ensuring the discharges of high quality wastewater effluents into receiving water bodies and consequence, a healthier environment. Due to massive worldwide increases in human population, water has been predicted to become one of the scarcest resources in the 21st century, and despite large advances in water and wastewater treatments, waterborne diseases still pose a major threat to public health worldwide. Several questions have been raised on the capacity of current wastewater treatment regimes to remove pathogens from wastewater with many waterborne diseases linked to supposedly treated water supplies. One of the major gaps in the knowledge of pathogenic microorganisms in wastewater is the lack of a thorough understanding of the survival and persistence of the different microbial types in different conditions and environments. This therefore brings to the fore the need for a thorough research into the movement and behavior of these microorganisms in wastewaters. In this review paper we give an overview of wastewater treatment practices with particular emphasis on the removal of microbial pathogens.

KENYA'S DESTINATION IMAGE: PERCEPTIONS OF KENYA AS A PREMIER DESTINATION OF AFRICA

The purpose of the paper was to investigate the perceptions of Kenya as a premier destination in Africa by potential visitors from the United Kingdom source market. The article specifically looked at the perceptions before actual visitation by the prospective visitors. United Kingdom has over the years been one of the key source markets for tourists for Kenya. An understanding of the perceptions held by potential tourists is an important tool for marketers to re-brand Kenya and give it a new image that will among other things ensure continued growth of the industry. There is dearth of research in destination image on UK perspective on Kenya as a tourist destination. It is expected that the results of the study will lead to better strategies for tourism growth in the wake of global competition in the industry. The study was cross-sectional survey carried out in selected locations of the city of Glasgow in Scotland among prospective visitors to Kenya where face to face random sampling was used. Data was collected using a self administered questionnaire and analysed using quantitative and qualitative techniques. The results indicate that the perceptions of Kenya as a premier destination of Africa are positive. The research was only limited in the city of Glasgow in Scotland thereby representing a fraction of the entire source market. A large sample would have been appropriate from several cities in Europe. The fact that Kenya bears a positive image as a premiere tourist destination in Africa despite the many calamities and destination issues that have affected it such as terrorism, political violence and others, it is imperative for the government and other key players to put good competitive strategies in place in order to not only increase the tourist arrivals from diverse markets but also to increase tourism revenues.
À la recherche de la langue perdue : étude psycholinguistique de l'attrition de la première langue chez des Coréens adoptés en France

Does exposure to a particular language leave permanent traces in the brain? It is possible for a second language (L2) to replace a first language (L1), under special circumstances? In this thesis we explore the possible remnants of the L1 acquired and "lost" during childhood, as well as competence in the L2 acquired later in life. In order to address these issues, we have chosen to study young adults of Korean origin adopted by French-speaking families during childhood. Our subjects were adopted between the ages of 3 and 10 years and have been severed from the Korean language and culture since their adoption 15 to 30 years earlier. This thesis is comprised of three sections : 1. ) the search for linguistic and other memory traces related to the adoptees'life in Korea; 2. ) the search for remnants of Korean phonology, and 3. ) the evaluation of certain aspects of French. Our findings show that the Korean adoptees have become like native French-speakers in their language processing abilities, suggesting either a loss of Korean, or an important inaccessibility to this language.
Estimation of tool wear of a gun drill using the signal curve pattern of feed force

This study concentrates on gundrilling and the related feed force signal in time domain, and possibilities of using this signal in drill wear monitoring. The behavior of the feed force was studied in a normal gundrilling procedure, and also in a situation where the feed was stopped just before guidance feed was replaced by actual drilling feed. Stopping the feed caused a new kind of behavior in the pattern of the feed force curve, which could be used in monitoring the extent of drill wear. Regression models were created in order to estimate the mean flank wear in the cutting edges, flank wear in the drill tip, and longitudinal wear based on the pattern of the feed force curve when cutting conditions remain constant. Based on the test results, it was concluded that from the pattern of the feed force curve monitored in time domain and modified by stopping the feed, it is possible to predict the extent of the wear of the gun drill.
Economic Value Added: A Better Technique for Performance Measurement

Measuring performance in a day to day business to corporate managers. The job is very much important for corporate performance also. Rewarding out performers and treating under performers are today’s norm to establish equity to work place. Aptly, lots of techniques have been developed so far to address this issue. Each technique has its own parameters and conceptual underpinning. Conceptualization of techniques with their limitations and challenges are very much important before their application. This paper gives an overview of different performance measures emphasizing Economic Value Added (EVA). An attempt is made to compare EVA with other performance measures to give the readers a more focused orientation with the EVA. Literature review is used as a methodology with qualitative orientation of research. Keywords: Performance measures, Economic Value Added, Residual Income, Market Value Added and Return on Investment.
Biotechnological production of -amylases for industrial purposes: Do fungi have potential to produce -amylases?

Enzymes are substances produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction. Amylases are a class of hydrolytic enzymes, widely spread in nature having varied application in different industrial processes and constitute a class of industrial enzymes. Fungal amylases have been widely used for the preparation of oriental foods. In spite of the wide distribution of amylases in nature, fungal amylases are used for industrial production due to advantages such as cost effectiveness, consistency, less time and space required for production and generally regarded as safe (GRAS). Due to the increasing demand for these enzymes in various industries, there is enormous interest in developing enzymes with better properties such as raw starch degrading amylases suitable for industrial applications. Penicillium and Aspergillus produces a large variety of extracellular enzymes, of which amylases and proteases are of significant industrial importance and serve in the production of a number of biotechnologically produced enzymes. Key words: α-Amylase, Penicillium, Aspergillus, enzyme, hydrolytic.
Comparisons of thermospheric high-latitude nitric oxide observations from SNOE and global auroral X-ray bremsstrahlung observations from PIXIE

[1] Three years (March 1998 through March 2001) of nitric oxide (NO) observations in the Northern Hemispheric thermosphere (90-170 km) as made by the Student Nitric Oxide Explorer (SNOE) spacecraft are compared in a broad statistical analysis with the daily-averaged northern auroral bremsstrahlung x-ray observations, which are taken to be a good proxy for the population of precipitating energetic electrons. The latter are made by the Polar Ionospheric X-ray Imaging Experiment (PIXIE) on board the NASA GGS Polar spacecraft. A modest correlation between these two data sets is found, indicating that about 20-40% of the variation in the number density of thermospheric nitric oxide at high latitudes is caused by variations in the precipitation of energetic particles from the magnetosphere into the auroral regions of the ionosphere. Time delays between the two data sets are examined in this study, as well as the altitude profile of the nitric oxide observations. Differences in the response and recovery times in the two data sets are also carefully considered along with hemispheric asymmetries as a function of season, leading to stronger correlations which are then discussed in terms of the properties of the data sets used.
Morphological structure through lexical parsability

The emergence of morphological structure in lexical acquisi- tion is analysed in the computational framework of Temporal Self-Organ- ising Maps (TSOMs), to provide an explanatory basis for both psycholin- guistic and linguistic accounts of lexical parsability. The investigation we propose is grounded on the hypothesis that perception of morphological structure (parsability) and frequency strongly correlate in the acquisition of inflectional paradigms. Analysis of experimental results of word acqui - sition obtained by artificially varying training conditions, allows us to un - derstand developmental competition between fully-inflected word forms, and to investigate a hierarchy of frequency effects. The computational and theoretical implications of such a memory-based view of the relation- ship between frequency and perception, and its potential to account for long-term morphological effects in lexical acquisition are illustrated.
Binary-amplitude modulation based super-oscillatory focusing planar lens for azimuthally polarized wave

Tight focus of azimuthally polarized wave finds its applications in optical super-resolution, particle trapping and so on. To overcome the disadvantages of conventional optics, including bulky size and difficult for integration, a binary-amplitude (0, 1) super-oscillatory planar lens is designed for sub-diffraction focusing of azimuthally polarized wave at wavelength of 632.8 nm. The lens radius is 650λ, and its focal length is 200λ. The corresponding numerical aperture is 0.96. The experimental results demonstrate the generation of a hollow spot with circular ring shape on the focal plane. The inner full-width-at-half-maximum of the hollow spot is 0. 368λ, smaller than the super-oscillatory criterion (0.398λ), and the maximum sidelobe ratio is about 36.7%. Such planar lenses are easy to fabricate. Their small size and ultra-thin thickness make them promising in system minimization and integration for different applications, such as optical microscopy, optical trapping and ultra-high density data storage.
Estimation of GEOS-Chem and GOCART Simulated Aerosol Profiles Using CALIPSO Observations over the Contiguous United States

ABSTRACTModel-simulated aerosol profiles can significantly improve a satellite’s capability to estimate ground-level particle concentrations, but are difficult to validate due to the sparse network of ground-based lidars. We quantitatively evaluated aerosol vertical profiles simulated by the Global 3-D Atmospheric Chemical Transport model (GEOS-Chem) and the Goddard Chemistry Aerosol Radiation and Transport model (GOCART) over the contiguous United States using the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO). Model-simulated and satellite-retrieved Aerosol Optical Depth (AOD) are first validated with the Aerosol Robotic Network (AERONET) data. The large discrepancies between satellite and model are due to underestimation of GEOS-Chem AOD in the West and GOCART AOD in the East, along with overestimation of CALIPSO AOD during winter and in the West. Model-simulated Aerosol Extinction Coefficients (AEC) at three layers are evaluated against CALIPSO. Aggregating the data from daily and 2 × 2.5 degree model resolutions to a national or annual scale can significantly improve the correlation coefficient and regression slope. Both GEOS-Chem and GOCART underestimate AEC in the lower troposphere in the East, and in the free troposphere in the West than CALIPSO. We attribute these differences to the coarse horizontal resolution, missing aerosol components, and inappropriate emission inventory of the models. Additionally, the low signal-to-noise ratio and cloud and bright surface reflectance interfere with the satellite’s measurements.
Nitrogen oxides in the global upper troposphere: interpreting cloud-sliced NO2 observations from the OMI satellite instrument

Abstract. Nitrogen oxides (NOx≡NO+NO2) in the upper troposphere (UT) have a large impact on global tropospheric ozone and OH (the main atmospheric oxidant). New cloud-sliced observations of UT NO2 at 450–280 hPa (∼6–9 km) from the Ozone Monitoring Instrument (OMI) produced by NASA and the Royal Netherlands Meteorological Institute (KNMI) provide global coverage to test our understanding of the factors controlling UT NOx. We find that these products offer useful information when averaged over coarse scales (20∘×32∘, seasonal), and that the NASA product is more consistent with aircraft observations of UT NO2. Correlation with Lightning Imaging Sensor (LIS) and Optical Transient Detector (OTD) satellite observations of lightning flash frequencies suggests that lightning is the dominant source of NOx to the upper troposphere except for extratropical latitudes in winter. The NO2 background in the absence of lightning is 10–20 pptv. We infer a global mean NOx yield of 280±80 moles per lightning flash, with no significant difference between the tropics and midlatitudes, and a global lightning NOx source of 5.9±1.7 Tg N a−1. There is indication that the NOx yield per flash increases with lightning flash footprint and with flash energy.
Implementation and Demonstration of a Building Simulation Based Testbed for Assessment of Data Centre Multi-domain Control Strategies

The traditional data centre (DC) infrastructure is being significantly extended by modern information technology (IT) trends on one side, and lasting calling for DC sustainability on the other. A holistic DC management will be necessary to coordinate different DC processes and to dock the DC environment into modern cities and district infrastructure. A development of such a complex management requires comprehensive testing possibilities. The testing is hardly possible on the real DC infrastructure due to the mission critical nature. Building energy modelling methods offer a suitable platform for the development of a safe and reliable testing environment. This paper deals with new application of Building Energy Simulation (BES) method and introduces a workflow for virtual closed-loop testing of enhanced multi-domain operation for data centres
Realization of Semantic Integration of the 3-D Data in Different 3D Virtual Communities with Ontology Matching

By extracting the semantic information and the intention of the operation which exist in the three-dimensional virtual community space with using ontology and defining it specifically systematically, we had shown the modeling technique that it was managed with DB with separating semantic information and 3-D shape data. Ontology has generally commonness, agreement as a nature. By combining ontology and 3-dimensional space, the 3-dimensional virtual community integrated by one ontology has been designed. In this case, the ontology is designed with a original viewpoint and interest in the space is generated in one community space. But it is not built in consideration of the meaning or intention of different community space, the reference or operation accompanied by the meaning cannot be performed to the 3-dimensional data object of different space. Therefore, we show that inquiry which had a meaning and an intention also to the 3-dimensional data object of different virtual space can be performed with ontology matching in this paper.

Essential Oil Composition and Antimicrobial Activity of the Oil and Extracts of Bunium persicum (Boiss.) B. Fedtsch.: Wild and Cultivated Fruits

Background: Fruits of Bunium persicum (Boiss.) B. Fedtsch (Apiaceae) has been used as spice, anti-flatulence and antiseptic agent for many years. In recent years the wild resources of the plant have been threatened by extinction. Domestication of such a plant saves its genetic resources from depletion. However, concerns remain about the possible changes due to development of chemotypes and changes in the composition and biological and pharmacological potentials. Methods: Analyses of essential oils from fruits of wild and cultivated types was performed using Gas Chromatography/Mass Spectroscopy. Antimicrobial assessment was done by agar diffusion method Results: The main compounds of both oils were included γ-terpinene (30.77% and 27.57%), cuminaldehyde (20.49% and 21.1%), ρ-cymene (20.1% and 18.32%) and γ-terpinen-7-al (8.29% and 7.84%) respectively. Analytical results of both tested oils exhibited very close similarities in major compounds, whereas some differences in their percentages were observed. In vitro antimicrobial evaluation of volatile oils, total extract and the resultant fractions against Staphylococcus aureus, Escherichia coli and Candida albicans demonstrated some similarities and differences. Minimum inhibitory concentrations (MICs) of wild grown fruits essential oils ranged between 0.375-1.5 mg/ml, while those of cultivated one were 0.75-6.25 mg/ml. All extracts and fractions showed similarly minor antibacterial potential while anti-Candida albicans activity was much remarkable with MICs calculated 2.5-5 mg/ml for cultivated and 5 mg/ml for wild grown extracts and fractions. Conclusion: In conclusion, despite the substantial similarities in composition of both oils, the alteration in antimicrobial results may be caused by variety in concentration of major and minor compounds and their synergism or antagonism in mixture.
A NEW SECTION OF BEGONIA ( BEGONIACEAE ) FROM WEST CENTRAL AFRICA

Previous analyses of macromorphological and molecular data on the continental African species Begonia iucunda (Begoniaceae) suggest that it occupies an isolated phylogenetic position within a clade consisting otherwise of species in sections Cristasemen, Filicibegonia, Loasibegonia and Scutobegonia. Accordingly, the new monotypic section Chasmophila is here described. Its taxonomic position and relationship to other African sections are discussed and data on its distribution and ecology are presented.
Silicate solvated by an organic solvent as electrolyte or electrode material

Preparation and properties of silicate gels solvated by organic solvents as electrolytes or electrode materials were summarised. A silicate matrix based on tetraalkoxysilane, trialkoxysilane modified with organic groups or a mixture of these two, modified by organic solvents or solutions is the principal component of all the systems studied. The material used as the electrolyte is filled with a salt solution in an organic polar solvent or in the case of hybrid organic-inorganic silicate matrix it is functionalised with tetraalkylammonium groups with a pure solvent. The electrodes are made of a composite material consisting of graphite particles, silicate matrix functionalised with methyl groups and filled with a pure or diluted redox liquid.
Japanese EFL University Students and the Study Abroad Experience: Examining L2 Development and Program Satisfaction after Three Weeks in North America

This study is designed to shed light on the study abroad experiences of Japanese EFL university students with two goals in minds: to measure the effects of short-term study abroad on L2 proficiency in this context, and to provide EFL/ESL professionals with information that can help them develop practices to improve their study abroad programs. 98 university student participants were divided into five groups consisting of four experimental groups who studied abroad and one control group who stayed at home. Each group was given L2 proficiency tests at two points in time: prior to four of the groups embarking on three-week study abroad programs, and after the four groups returned from their time abroad. In addition, post-study abroad questionnaires and interviews were administered to assess students’ attitudes and activities during the treatment period. The findings demonstrate that short-term study abroad did not have a great impact on students’ TOEFL PBT scores and also provide detailed information to help study abroad professionals around the world better understand the wants and needs of Japanese EFL university students. The authors discuss the implications of these findings and offer some suggestions for study abroad professionals and researchers to consider moving forward.
