Understanding the Meaning of Images

The ability to process visual details is one of the most interesting parts of the nervous system. Humans have the ability to quickly analyse and understand the meaning behind a situation depicted in an image or video capture. This capacity is essential because it allows us to carry out different tasks in our every day lives. Training machines to recognise and tell the story behind an image can greatly benefit our lives. The importance of this research topic can be observed in areas such as surveillance, driving assistance and human-machine interaction.
Using Government Microblogs to Enhance Citizen Engagement Completed Research

Utilizing the Technology-Organization-Environment (TOE) theory and the literature on citizen engagement, this article examined the contextual antecedents of the activities of government agencies in government microblogs and explored the relationship between the activities of government agencies in government microblogs and citizen engagement, as well as analyzed the moderating role of satisfaction and citizen pressure on this relationship. Based on archival data from 284 cities in China, our results showed that some of TOE contextual factors had positive influences on the activities level of government agencies in government microblogs. Further, the activities of government agencies in government microblogs are positively associated with the extent of citizen engagement. Results also indicated that satisfaction and citizen pressure negatively moderated this relationship. Our findings provide indications to practice on enhancing citizen engagement in implementing relevant government microblogs initiatives.
Locus of control and job satisfaction as predictors of Perceived non-teaching staffs ` productivity in higher institutions in Ogun state , Nigeria

The study investigated the influence of locus of control and job satisfaction on perceived nonteaching staffs` productivity in higher institutions in Ogun State of Nigeria. This is for the purpose of ascertaining the relative and combined contributions of locus of control and job satisfaction to perceived nonteaching staffs` productivity in higher institutions in Nigeria. A descriptive survey research design was adopted for the study. A total of 341 respondents were selected for the study, using proportionate stratified sampling technique. The instruments used for data collection are structured questionnaires titled “Locus of Control Scale (LCS), Job Satisfaction Scale (JSS) and Workers` Productivity Scales (PWPS). The hypotheses generated for the study were tested at 0.05 alpha levels using Regression Analysis and Pearson Product Moment Correlation Statistics. The findings of the study revealed that locus of control and job satisfaction were found to have jointly contributed to perceived nonteaching staffs` productivity in selected higher institutions in Ogun State of Nigeria. Also, job satisfaction was found to have significantly influenced perceived nonteaching staffs` productivity. Moreover, locus of control was not significantly related to perceived nonteaching staffs` productivity. Based on the findings of the study, it is recommended that nonteaching staffs` should be exposed to skill development programme on the job and on continuous basis in order to update their skills, knowledge, values, and receive proper orientation regarding the correlate of organizational productivity. This will enable them aware of the influence of the working environment on their productivity and aver the danger of attributing productivity to self efficacy and locus of control.
Excretable IR-820 for in vivo NIR-II fluorescence cerebrovascular imaging and photothermal therapy of subcutaneous tumor

Rationale: Cerebrovascular diseases, together with malignancies, still pose a huge threat to human health nowadays. With the advantages of its high spatial resolution and large penetration depth, fluorescence bioimaging in the second near-infrared spectral region (NIR-II, 900-1700 nm) and its related imaging-guided therapy based on biocompatible fluorescence dyes have become a promising theranostics method. Methods: The biocompatibility of IR-820 we used in NIR-II fluorescence bioimaging was verified by long-term observation. The model of the mouse with a cranial window, the mouse model of middle cerebral artery occlusion (MCAO) and a subcutaneous xenograft mouse model of bladder tumor were established. NIR-II fluorescence cerebrovascular functional imaging was carried out by IR-820 assisted NIR-II fluorescence microscopy. Bladder tumor was treated by NIR-II fluorescence imaging-guided photothermal therapy. Results: We have found that IR-820 has considerable NIR-II fluorescence intensity, and shows increased brightness in serum than in water. Herein, we achieved real time and in vivo cerebrovascular functional imaging of mice with high spatial resolution and large penetration depth, based on IR-820 assisted NIR-II fluorescence microscopy. In addition, IR-820 was successfully employed for NIR-II fluorescence imaging and photothermal therapy of tumor in vivo, and the subcutaneous tumors were inhibited obviously or eradicated completely. Conclusion: Due to the considerable fluorescence intensity in NIR-II spectral region and the good photothermal effect, biocompatible and excretable IR-820 holds great potentials for functional angiography and cancer theranostics in clinical practice.
Improving Indoor Localization Based on Artificial Neural Network Technology

Wireless networks are ubiquitous nowadays and hence provide a promising approach for indoor localization. Many algorithms have been proposed for exploiting wireless signals for localization purposes. Among the methods, ANN-based methods have attracted particular attention due to their robustness in complex signal environments. However, their accuracy is still degraded by multi-path effects, signal fluctuations, and so on. Accordingly, this study commences by examining the effects of fluctuations in the received signal strength indicator (RSSI) measurement on the accuracy of an ANN-based localization algorithm. This study list some strategies and illustrate by simulation exper-iment. Based on the investigation results, a systematic methodology is proposed for improving the localization performance by increasing the number of APs. The feasibility of the proposed method is demonstrated by means of numerical simulations
Mutagenesis of 16 S rRNA C 1409-G 1491 Base-pair Differentiates Between 6 0 OH and 6 0 NH 3 C Aminoglycosides

0022-2836/$ see front matter q 2004 E † P.P. & S.H. contributed equally Abbreviations used: MIC, minim concentrations; RDP, ribosomal dat dissociation constants. E-mail address of the correspond boettger@immv.unizh. ch Using a single rRNA allelic Gram-positive model system, we systematically mutagenized 16 S rRNA positions 1409 and 1491 to probe the functional relevance of structural interactions between aminoglycoside antibiotics and the A-site rRNA that were suggested by X-ray crystallography. At the structural level, the interaction of the 2-deoxystreptamine aminoglycosides with the rRNA base-pair C1409-G1491 has been suggested to involve the following features: (i) ring I of the disubstituted 2-deoxystreptamines stacks upon G1491 and H-bonds to the Watson–Crick edge of A1408; (ii) ring III of the 4,5-disubstituted aminoglycosides shows hydrogen bonding to G1491. However, we found that mutants with altered 16 S rRNA bases 1409 and 1491 discriminated poorly between 4,5disubstituted and 4,6-disubstituted 2-deoxystreptamines, but differentially affected aminoglycosides with a hydroxyl group versus an ammonium group at position 6 0 of ring I, e.g. G1491U conferred high-level drug resistance to paromomycin and geneticin, but not to neomycin, tobramycin or gentamicin. q 2004 Elsevier Ltd.

EXACT CONTROLLABILITY OF THE EULER-BERNOULLI PLATE WITH VARIABLE COEFFICIENTS AND SIMPLY SUPPORTED BOUNDARY CONDITION

This article studies the exact controllability of an Euler-Bernoulli plate equation with variable coefficients, subject to the simply supported boundary condition. By the Riemannian geometry approach, the duality method, the multiplier technique, and the compactness-uniqueness argument, we establish the corresponding observability inequality and obtain the exact controllability results.
The Extent of Repetition in Contract Language

Contract language is repetitive (Anderson and Manns, 2017), but so is all language (Zipf, 1949). In this paper, we measure the extent to which contract language in English is repetitive compared with the language of other English language corpora. Contracts have much smaller vocabulary sizes compared with similarly sized non-contract corpora across multiple contract types, contain 1/5th as many hapax legomena, pattern differently on a log-log plot, use fewer pronouns, and contain sentences that are about 20% more similar to one another than in other corpora. These suggest that the study of contracts in natural language processing controls for some linguistic phenomena and allows for more in depth study of others.
Coporate Governance Mechanisms and Accounting Conservatism

The separation of ownership from management and the existence of creditors results in information asymmetry among stakeholders to the firm. Management may pursue interest different from that of other stakeholders; hence, the demand for conservative reporting. This study examines the effects of corporate governance mechanisms on accounting conservatism in the Nigeria food and beverages sector. This study focuses on CEO duality, board size, board composition and managerial shareholding as proxies for corporate governance mechanisms. The negative accrual measure of conservatism was employed in estimating conservatism. Data for the study was obtained from the Nigerian Stock Exchange Fact Book and the companies’ annual report for the period 2003 to 2010. The extent of the influence of our corporate governance proxies was estimated using regression method of analysis. Our result reveals a significant negative influence of board size and a significant positive influence of independent directors on the board on conservative reporting. Therefore, we recommend that boards of listed food and beverages firms should be composed more of independent directors. Also, smaller board sizes should be adopted by Nigeria food and beverages firms in other to improve realization of accounting numbers.
Nuclear Liquid Gas Phase Transition and Nuclear Zipf Law

Nuclear Zipf’s law has been proposed for the studies of the nuclear disassembly and liquid gas phase transition. In this report, firstly we use the isospin dependent lattice gas model and molecular dynamical model to define the nuclear Zipf-type plot according to the fragment mass (charge) hierarchy and predicts that there exists the nuclear Zipf law, namely the mean mass (charge) of the cluster shows inversely to its rank from the largest size to the smallest size, around the nuclear liquid gas phase transition. Secondly we show the experimental evidences for nuclear Zipf’s law in the quasi-projectiles fragmentation data of Ar beams by NIMROD multidetector as well as in the analysis of CERN emulsion data of Pb + Pb or Plastic at 158 AGeV or lower energies.
Data Encryption Scheme for Large Data Scale in Cloud Computing

Cloud computing is a power full platform to deliver applications over the internet or a private network. It considers the next technology in data manipulating and retrieving. These technologies help to manage and manipulate data in various services and deployment models. The cloud services are delivered from cloud computing providers to the users in a manner of leased service which give users an ability to lease services in a specific scope. To handle the huge data in today’s scenario, data cloud storages is suggested which gives a big relief for users as in local machines. Data protection is one of the most important issues in cloud computing. The researchers present many techniques, for data protection and security schemes such as Intrusion Detection Systems (IDS’s), Access Control, Encryption and Secure Socket Layer (SSL), but the data security is still a challenging issue. The goal of this paper is to present the security techniques for cloud computing in different cloud services model. Furthermore, we propose a security data encryption technique for cloud services in SaaS model for large data scale. Salesforce.com SaaS service model provides a good tool for the users to register in the cloud and develop their applications.
A REVIEW OF ROBOTIC SURGERY EVOLUTION , CURRENT APPLICATIONS AND FUTURE PROSPECTS

The aim of this paper is to review the background of robotic surgery, the existing technology associated with this field, the main robotic surgical procedures, the training methods, the financial aspect of using these systems and future prospects for robotic-assisted surgery. Given the fact that robotic surgery has a history of only 30 years, the surgical possibilities are not researched to their full extent. The most appreciated feature of the robotic system is considered to be the high mobility and wide array of movement allowing access to do surgery on tissues inaccessible to classical approaches. With regards to the downside of this technique, it’s almost unanimous accepted that it’s cost related. To write this article over 60 literature sources about the history and development of surgical robots also concerning case studies, animal and human trials and their results obtained throughout the past few years were reviewed. Numerous trials that analyze new surgical applications are undergoing and although the system has been mainly used for soft tissue small interventions, its limits are yet to be determined.
Voice Quality : the 4 th Prosodic Dimension

This paper presents data from an analysis of a large conversational-speech corpus, showing evidence that voice quality, as measured on a continuum from pressed to breathy using a normalized amplitude quotient (NAQ), is varied consistently, and in much the same way as, but independently of, fundamental frequency, to signal paralinguistic information. We show that interlocutor, speaking-style, and speech-act all have significant interactions with NAQ, and argue that voice-quality should be considered as the 4 prosodic parameter, along with pitch, power, and duration.
Language selection in code-switching : An analysis of nouns from Romanian-English code-switching

Bilinguals have multiple linguistic representations for a concept, corresponding to each language (Bialystok, 2007). Thus, in the process of lexical selection, bilingual speakers have to choose between lexemes that share semantic representations across the two languages. Experiments have shown that there is between-language competition in the process of lexical selection, both from the first to the second language and vice-versa, even in late bilinguals who are dominant in their first language (Marian and Spivey, 2003). Because most concepts are associated with synonymous, equally activated lexical nodes, bilinguals should encounter significant difficulties in lexical selection, yet it does not seem to be the case. Whether it is the case that bilinguals select just from the target lexicon, activate just the target lexicon, or suppress the lexicon that is not targeted, proficient bilinguals can speak clearly and effortlessly in one language and not the other (Finkbeiner, Gollan, and Caramazza, 2013).
Antitumor Activity of Citrusmaxima ( Burm . ) Merr . Leaves in Ehrlich ’ s Ascites Carcinoma Cell-TreatedMice

Context. The plant Citrus maxima Merr. (Rutaceae), commonly known as shaddock or pomelo is indigenous to tropical parts of Asia. The objective of present study is to evaluate the methanol extract of Citrus maxima leaves for its antitumor activity against Ehrlich’s Ascites Carcinoma cell in Swiss albino mice. Experimental design. The antitumor activity of methanol extract of Citrus maxima leaves (MECM) was evaluated against Ehrlich Ascites Carcinoma (EAC) cell line in Swiss albino mice. 2 × 106 cells were inoculated in different groups of animals. MECM (200 and 400 mg/kg BW i.p.) was administered for nine consecutive days. On day 10th half the animals of different groups were sacrificed for determination of tumor and haematological parameters and the rest half were kept with sufficient food and water ad libitum for determination of increase in life span. Result and Discussions. Oral administration of the extract at the doses of 200 and 400 mg/kg significantly decreased tumor parameters such as tumor volume, viable tumor cell count and increased body weight, hematological parameters and life span in respect of the EAC control mice. Conclusion. Experimental design exhibits significant antitumor activity of the extract (MECM) in a dose dependant manner.
CFD CODE VALIDATION OF ROTOR/FUSELAGE INTERACTION USING THE COMMERCIAL SOFTWARE STAR-CCM+8.04

In this paper the commercial CFD software package STAR-CCM+ 8.04 was validated against wind tunnel experiments and a qualitative comparison to a non-commercial code was made. NASA’s generic ROBIN helicopter model was adopted for transient simulations to study Rotor-Body interaction (ROBIN). Two different CFD methods have been applied to model the main rotor rotation and the cyclic blade pitching. The first method uses a sliding interface approach where the volume around the entire rotor is modelled in a cylindrical region with a rotating mesh. The cyclic blade pitching has been modelled with a morphing mesh inside that rotating mesh region. The second method uses an overset grid approach where the volume around each blade is modelled in an individual overset grid region. In both methods the rotor rotation is resolved with 1 degree per timestep. The compressible ideal gas flow is solved with a classical ReynoldsAveraged-Navier-Stokes (RANS) solver by implicit spatial integration in an unsteady analysis, using a coupled algebraic multi-grid method with a courant number of CFL = 30. Turbulence is modelled with the well known SST (Menter) Komega model with 2 nd order convection. The helicopter is in straight forward flight with an advance ratio of μ = 0.15. Computational results were compared to NASA’s existing experimental results. In the simulations the results became quasi periodic between the 2 nd and 3 rd rotation; 5 full rotor rotations were simulated. It was concluded that computational results for both motion modelling methods were in good agreement with unsteady pressure measurements at various locations along the fuselage. Along the top centreline over the nose and tail boom the periodic pressure fluctuations induced by the blade passages over one full rotor rotation were in good agreement with the experiments. In accordance with the experiments it was also found that the magnitude of the pulse increases with the thrust coefficient. The CFD simulations revealed detailed flow features surrounding the rotor and the fuselage. Detailed sections of the vorticity field and isosurfaces of the q-criterion reveal the propagation of the blade tip vortices until far downstream of the fuselage. This flow structure is also in good agreement with computational results from studies carried out with non-commercial CFD codes. The method presented using STAR-CCM+ 8.04 is capable to model the complex motion of helicopter rotor blades and predict the flow field and is a promising tool for future analysis of helicopter aerodynamics.
Utilization of Agricultural Residues as Local Alternative Energy to Woodfuel in Sudano-Sahelian Northwestern Nigeria

The recourse to agricultural residues for meeting energy needs in the Sudano-Sahelian northwestern Nigeria is necessitated vis-à-vis dwindling access to woodfuel and the rapidly growing population. This paper did an inventory on the local alternatives to woodfuel being utilized in the rural energy system of the SudanoSahelian northwestern Nigeria. It also examined sources of the local alternatives its sustainability. Both multistage cluster and systematic sampling procedures were employed in selecting the 22 settlements for the study. Data was generated from review of documents, Focus Group Discussions (FGDs), semi structured interviews (SSI) and photographs; 440 people were purposively selected for the FGDs and grouped by age and sex. The data generated were analyzed using descriptive statistics, SPSS (analysed using the frequencies, percentages and cross tabulation) and content analysis. Results were presented in tables as appropriate. The local alternatives were mostly utilized in cooking, and heating. High woodfuel demand and consumption has led to serious destruction of forest resources consequently resulting in the reduction or extinction of some of the tree species. Energy is vital for development; a great influence in the progress of a community, sustainability should be encouraged through curbing deforestation practices among others.

Assessment of heavy metal content and leaching characteristics of ash from a coal-fired power plant in Romania

The study investigates the heavy metal content of ash from one major coal-fired power plant in South-Western Romania. The ashes were analysed for the presence of As, Cu, Pb, Zn, Ni, Cr, Mn, Co, V, Mo, Ba, Cd, Hg. Major, minor and trace element concentrations in solid samples were determined by means of XRay Fluorescence (XRF), Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). Detectable levels over 100 ppm of some of the minor elements were found in ash recovered from the waste dumps. In this regard, experimental results indicate that toxic trace metals may leach out and contaminate soils as well as surface water and groundwater. This can generate health, environmental and land-use problems. The leachates were analyzed using ICP-MS and ICP-OES. Leaching tests that were performed showed that total solubilised substance (TDS) and heavy metals are below the limits of Romanian Ministry Order (RMO) 2005/95, on waste acceptance criteria for disposal in landfills. Key-Words: Coal ash, Combustion, Heavy metal, Leaching
DESTRUCTION OF ATTACKS WITH MH 2-AODV ROUTING PROTOCOL IN VEHICULAR AD-HOC NETWORK

Vehicular Ad-hoc Networks (VANET) are inaugurating for the purpose of communication among the moving vehicles over a constrained environment. Vehicles are subjected to move at high speed and hence they often face changes in their topology and frequent disconnections [1]. Due to these reasons routing remains as the major challenge in VANET. And one more challenge is that providing security, since various attacker’s involvement in the network will degrade the network performance. Hence enormous routing and security related algorithms / methods were proposed in state–of–the–art research work. VANET also involves with grouping of vehicles, which is said to be as clustering.
