A Method to Provide Cellular QoS for Tethered Clients

A host device includes a quality of service (QoS) access control module to establish and manage connections having levels of QoS between tethered devices and a network. The QoS access control module authenticates a tethered device to ensure that the tethered device is authorized to use a connection having the requested QoS, establishes a network route and rules for accessing the connection and establishes a secure connection between the host device and the tethered device. As a result, in some cases, the system prevents erroneous operation due to tethered devices attempting to perform tasks that require a connection having a certain QoS without receiving a network connection having that QoS

Language Assistant Capability Exchange Protocol

This disclosure describes techniques to support language assistance services for communication between devices. Per techniques of this disclosure, language assistant capabilities are exchanged between participating devices during call setup. A call protocol such as session initiation protocol (SIP) is suitably modified to exchange language assistant parameters during call set up. The SIP header fields are extended to add a parameter to indicate language assistant capabilities by indicating a suitable language code. An INVITE request is transmitted from an originating device that includes a language identifier that indicates the language assistant capabilities of the originating device. A corresponding language identifier of the terminating device is requested. A language identifier for the terminating device is obtained from and transmitted to the originating device along with a RING message. When the call is answered at the terminating device, an updated language identifier may be provided along with an OK message

Asymmetric Relationship Between Reference Group Influence on Pro-Health and Deviant Behaviors of Base of Pyramid Consumers

This research draws from social capital and reference group theories to examine how they influence healthy eating and alcohol abuse of low-income consumers. Data from 711 rural Indian show that asymmetric relationship between structural and cognitive social capital on healthy eating versus alcohol abuse and informational/normative influence moderators

Does Information and Communication Technology Improve Job Satisfaction? The Moderating Role of Sales Technology Orientation

Empirical research concerning the role of information and communication technology (ICT) in shaping business-to-business salesforce job satisfaction remains relatively scarce. The authors propose and empirically test a causal model that theoretically represents structural relationships among factors comprising ICT and eventual salesperson job satisfaction. Study results indicate that ICT indirectly influences job satisfaction through salesforce administrative performance. While ICT infrastructure, training, and support positively relate to administrative performance, none of them influence outcome performance significantly. In addition, salesperson technology orientation moderates the effect of both ICT infrastructure and support on job satisfaction. Managerial insights and implications from the research are discussed

Microbial Status of Groundwater in and Around Cuddalore Town, Tamilnadu

Water is one of the abundantly available substances in nature. The groundwater is believed to be comparatively clean and free from pollution than surface water. But prolonged discharge of domestic sewage and industrial effluents causes the groundwater to become polluted and create health problems. Coliforms might cause intestinal disorders of the inhabitants and pilgrims. Ground water samples from 15 locations have been collected from Cuddalore Town including SIPCOT industrial area. The present study deals with the analysis of total Coliform count by most probable number (MPN) method and to identify the presence of gram negative or gram positive organisms. The bacteriological quality of groundwater had crossed the upper limits prescribed by WHO. The results found that the water in all these places was found to be unfit for human consumption due to contamination. Pollution control measures and strict enforcement of its laws have been recommended

Electrodeposition of Sn, Se, SnSe and the material properties of SnSe films

Tin sulphide (SnS) films have been electrodeposited and the materials properties are reported, The potential-pH diagram of Sn and S in aqueous medium are superimposed to obtain the common immunity domains which predicts a pH value 1.5 and deposition potential of ·1.0 VseE for the stoichiometric deposition. Films are cathodically deposited on 5002 coated conducting glass substrates at bath temperatures 303-353 K. XRD studies show the polycrystalline nature with orthorhombic structure. The optical band gap of the snS film is 1.1 eV from the absorption studies. ESCA spectrum confirms the presence of Sn and S on the grey black sample. Uniform, smooth and pin hole free surface morphology is observed by SEM

Ionospheric response to the corotating interaction region-driven geomagnetic storm of October 2002

Unlike the geomagnetic storms produced by coronal mass ejections (CMEs), the storms generated by corotating interaction regions (CIRs) are not manifested by dramatic enhancements of the ring current. The CIR-driven storms are however capable of producing other phenomena typical for the magnetic storms such as relativistic particle acceleration, enhanced magnetospheric convection and ionospheric heating. This paper examines ionospheric plasma anomalies produced by a CIR-driven storm in the middle- and high-latitude ionosphere with a specific focus on the polar cap region. The moderate magnetic storm which took place on 14–17 October 2002 has been used as an example of the CIR-driven event. Four-dimensional tomographic reconstructions of the ionospheric plasma density using measurements of the total electron content along ray paths of GPS signals allow us to reveal the large-scale structure of storm-induced ionospheric anomalies. The tomographic reconstructions are compared with the data obtained by digital ionosonde located at Eureka station near the geomagnetic north pole. The morphology and dynamics of the observed ionospheric anomalies is compared qualitatively to the ionospheric anomalies produced by major CME-driven storms. It is demonstrated that the CIR-driven storm of October 2002 was able to produce ionospheric anomalies comparable to those produced by CME-driven storms of much greater Dst magnitude. This study represents an important step in linking the tomographic GPS reconstructions with the data from ground-based network of digital ionosondes

Optimal configuration of microstructure in ferroelectric materials by stochastic optimization

An optimization procedure determining the ideal configuration at the microstructural level of ferroelectric (FE) materials is applied to maximize piezoelectricity. Piezoelectricity in ceramic FEs differ significantly from that of single crystals because of the presence of crystallites (grains) possessing crystallographic axes aligned imperfectly. The piezoelectric properties of a polycrystalline (ceramic) FE is inextricably related to the grain orientation distribution (texture). The set of combination of variables, known as solution space, which dictates the texture of a ceramic is unlimited and hence the choice of the optimal solution which maximizes the piezoelectricity is complicated. Thus a stochastic global optimization combined with homogenization is employed for the identification of the optimal granular configuration of the FE ceramic microstructure with optimum piezoelectric properties. The macroscopic equilibrium piezoelectric properties of polycrystalline FE is calculated using mathematical homogenization at each iteration step. The configuration of grains characterised by its orientations at each iteration is generated using a randomly selected set of orientation distribution parameters. Apparent enhancement of piezoelectric coefficient $d_{33}$ is observed in an optimally oriented BaTiO$_3$ single crystal. A configuration of crystallites, simultaneously constraining the orientation distribution of the c-axis (polar axis) while incorporating ab-plane randomness, which would multiply the overall piezoelectricity in ceramic BaTiO$_{3}$ is also identified. The orientation distribution of the c-axes is found to be a narrow Gaussian distribution centred around ${45^\circ}$. The piezoelectric coefficient in such a ceramic is found to be nearly three times as that of the single crystal.Comment: 11 pages, 7 figure
