The housing market plays a significant role in the economies of countries, and as an asset price channel, is considered as one of the main channels for monetary transmission mechanism. Considering the structure of the country's economy and the characteristics of housing as a capital commodity, the assessment of the impact of housing investment on inflation is important. This research evaluates ...

Each new medium (from print to television) has introduced a series of ratings technologies which, predominantly, quantifies the audience as passive commodity, i.e., as a number which is “delivered” by the broadcasters and “bought” by the advertisers. New electronic media demand a representation of audience that breaks with the traditional audience-as-commodity representation. Contemporary telev...

—In some scenarios such as catastrophes and military operations, there is a need for communication without an infrastructure. In urgent cases, in-time and reliable channel access must be ensured. However, the channel access delay in widely used CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) network increases unpredictably when the channel is sensed busy. Therefore, TDMA (Time...

in this article, the effectiveness of eight different technical indexes including simple moving average, weighted moving average, exponential moving average, relative strength, commodity channel, stochastic, money flow and demand are examined by comparison between indexes returns with buy and hold returns. the results shows the return of buy and hold strategy is more than technical indexes in t...

We propose a new class of channel allocation algorithms that are simple, robust and require no communication between interfering WLANs. We show they are provably correct and yet remarkably efficient under a wide range of network conditions and topologies. The algorithms are suited to implementation on standard equipment, requiring no special hardware support and making only light demands on com...

It opens wide of applications in fields healthcare, smart homes, robotics, human-media interaction, surveillance and security. WiFi-based solutions have received lot attention lately. These are based on idea nearby wireless signals affected by human bodies. Reflections p...

abstract in this paper an attempt is made to determine the most suitable agricultural commodities to be adopted for establishing a futures market in iran. two different approaches are adopted: the first involves identifying factors that contribute significantly to the success or failure of existing agricultural commodities futures contracts in established futures markets. the second involves si...

We propose a new type of optical fiber called homogeneous multi-core fiber (MCF) to drastically increase the transmission capacity of single fiber using the mode-division multiplexing. In this MCF, identical cores are closely arranged so that the cores are strongly coupled to each other to form coupled modes, each of which corresponds to a transmission channel. A novel mode multi/demultiplexer ...

We present a measurement study of how well 802.11n works in practice. Our goal is to understand the performance impact of the multiple antenna (spatial) techniques that are the key new capability of 802.11n. We experiment with a 10 node indoor testbed equipped with commodity Intel 802.11n NICs that have three antennas, i.e., 3x3 MIMO, and lowlevel instrumentation to let us to measure RF channel...

This study examines the impact of commodity price shocks on banking sector stability 18 African commodity-exporting economies using an unbalanced panel dataset spanning a 16-year period from 2000–2015. The economies’ sectors was estimated fixed effects model. empirical findings indicate that increase bank credit risk (non-performing loans) and, thus, pose to economies. results for disaggregated...
