Performance analysis of resource scheduling in LTE femtocell with hybrid access mode

Femtocell is a promising technology that intends in solving the indoor coverage problems so as to enhance the cell capacity. The overall network performance, in turn depends on the access methods used by the femtocells. The access method is used to identify about the user’s connectivity with the femtocell network. There are three access mechanisms defined in Third Generation partnership Project (3GPP) specification for Long Term Evolution (LTE) femtocells: open, closed and hybrid access mechanisms. Hybrid access mechanism is mostly preferred by the network for the effective utilization of resources. But, it is important to regulate the proper scheduling scheme for them. In this paper, scheduling in femtocell is investigated, where, among the non subscribers, preference is given to the users who have high throughput priority metric, thereby increasing overall throughput of the network

Investigations on global buckling behaviour of concrete-filled double-skinned steel tubular columns

[EN] Concrete-Filled Double-skinned Steel Tubular columns (CFDST) are proved to possess exceptional structural resistance in case of fire and multi-hazard situations. This superior quality of CFDST makes it preferable in long column applications. However, studies on the long column behaviour of CFDST is very few, and their results are not in line with the behaviour of CFST long columns. Whereas, several researches on stub column CFDST shows that, the axial compression behaviour of CFDST is similar to CFST. In this paper, selected results (4 numbers of circular CFDST specimens) from a large test data is presented. Axial compression behaviour of long column CFDST specimens is studied, with non-dimensional slenderness λ around 1.0, and hollowness ratio as the governing parameter for study. Test results namely, axial load carrying capacity, axial deformation and lateral deflection are presented in this paper. Numerical models are also developed and validated with the experimental results, to carry out more parametric studies. Further, the experimental axial capacity values are compared with modified capacity equations from EC4 and AISC. Results show that extended EC4 and AISC equations gives conservative predictions for CFDST column even in the long column range. Moreover, the initial imperfections in the specimen and their corresponding boundary conditions for load application, are found to be governing parameters in long column buckling study.Sulthana, UM.; Jayachandran, SA.

Studies on tuning surface electronic properties of hydrogenated diamond by oxygen functionalization

Ultra-wide bandgap and the absence of shallow dopants are the major challenges in realizing diamond based electronics. However, the surface functionalization offers an excellent alternative to tune electronic structure of diamonds. Herein, we report on tuning the surface electronic properties of hydrogenated polycrystalline diamond films through oxygen functionalization. The hydrogenated diamond (HD) surface transforms from hydrophobic to hydrophilic nature and the sheet resistance increases from ~ 8 kohms/sq. to over 10 Gohms/sq. with progressive ozonation. The conductive atomic force microscopic (c-AFM) studies reveal preferential higher current conduction on selective grain interiors (GIs) than that of grain boundaries confirming the surface charge transfer doping on these HDs. In addition, the local current conduction is also found to be much higher on (111) planes as compared to (100) planes on pristine and marginally O-terminated HD. However, there is no current flow on the fully O-terminated diamond (OD) surface. Further, X-ray photoelectron spectroscopic (XPS) studies reveal a redshift in binding energy (BE) of C1s on pristine and marginally O-terminated HD surfaces indicating surface band bending whilst the BE shifts to higher energy for OD. Moreover, XPS analysis also corroborate c-AFM study for the possible charge transfer doping mechanism on the diamond films which results in high current conduction on GIs of pristine and partially O-terminated HDs.Comment: 24 pages, 6 figures, 1 tabl

A CASE REPORT ON KARTAGENER'S SYNDROME

Kartagener’s syndrome is a rare congenital disorder consisting of situs inversus, bronchiectasis and sinusitis. It is a subgroup of immotile cilia syndrome called primary ciliary dyskinesia. In this syndrome generally male patients show infertility and reduced fertility in females. Mutation in DNAH5 gene located on chromosome 5p is responsible for this Mendelian disorder. Clinical manifestation involves recurrent respiratory infections and variability with multisystem involvement. Routine radiological tests are usually used for diagnosis. Prompt diagnosis and ideal management can prevent complications. Keywords: primary ciliary dyskinesia, situs inversus, bronchiectasis, dextrocardia

Formulation and evaluation of oxymetazoline hydrochloride nasal gels

The main intend of the implement sniff out formulate and evaluate oxymetazoline nasal gels. To achieve more persistent blood levels with decrease dosage of medicine by extended drug evidence and by passing hepatic initially cross metabolism and body including inferable disgrace. Mod FTIR & DSC spectra there is not any discrepancein the seam clean medicine, polymers & lipids. The Carbopol consisting of reinforce precail eventual scintillating moreover transparent Poloxamer, Hydroxy Propyl Methyl cellulose gels crop up prospective lucent as a consequence frosted slimy. The pH value of all developed formulations of gels (ONGF1-ONGF8) was in the range of 6.2 to 6.9. Spreadability of gels was in the range 19.51 - 33.91 g.cm/sec, The Viscosity of various formulated gels was found in range of 8628 to 9622 centipoises. The percentage drug content of all prepared gel formulations were found to be in the range of 78.53 to 98.56 %. The gel strength of all prepared formulations of gels was found to be in the range of 69 to 96 %. In-vitro diffusion drug release of Oxymetazoline Hydrochloride of nasal gels ONGF1 shows the 95% drug release.

Reinventing Traditional Practices for Sustainable Dwelling Solutions in Kerala

The need for sustainable architectural solutions has been identified as a priority by many present-day researchers and purpose of this study is to understand the relevance of traditional architecture in modern context. This paper deals with the study of architectural practices, which are traditionally practiced in Kerala region of India and to derive with cost effective sustainable solutions for future dwellings. Kerala experiences tropical warm humid climate and the traditional architectural styles found to be the direct responsive mechanism and adaptable solutions, using the available resources. The vision of Laurie baker had created an impact on the field and added a new dimension to the social imagination. The idea of well-being with reference to the western standards is disturbing the essence of social as well as economical sustainability, and which threatens the environmental balance as a whole. As architectural scenario in Kerala is undergoing drastic directionless changes in present period, a few design thoughts which would be the guiding force for the future is essential. This paper reviews the above aspects to conceive the ideas and solutions for sustainable dwellings in light of tradition.

Not AvailableThe deccani sheep breed is a source for coarse wool-cum-meat. Gongali/ kambali is a traditional multi-purpose blanket with coarse deccani fibres. On an account of declining institutional and government purchases, the market for the kambali has collapsed. Thus, innovative approaches towards the use of deccani wool fibre will improve value added products that have potential market, which not only helps to provide livelihood security to the rural people but also improves export from the country as well address the burning issues like increasing demand, restoration of endangered sheep breed of the Deccan plateau, employment generation in rural and semi urban areas and will open new avenues in the field of research. Keeping in view the above advantages, coarser deccani wool fibres were softened with protease enzymes in order to attain pliable and smooth fibers, in turn can get good handle fabrics, thereby improving its processing and utilization. Enzymes being natural products are completely bio-degradable and require low activation energy to soften the fibres for further usage with enhanced fibre properties. Therefore the present study was undertaken to assess the performance characteristics of the deccani wool fibers treated with enzymes (Papain and Pepsin with 1, 2 and 3 per cent concentration). Among all one percent concentration enzyme treatment to fibers was proven to be soften the fiber without much change in its tensile strength.CIWA- ICAR and PJTSA
