The effectiveness of Location Based Systems depends on the correct location of users and mobile devices. While the outdoor location can be easily calculated, using technologies such as GPS (Global Positioning System), it is more difficult to obtain when the location scenario is an indoor environment. Several technologies and location techniques can be used in this field. One of these techniques...

Principle Chromatographic procedures allow a separation of substance mixtures with the aid of a stationary separating phase and a mobile phase. In gas chromatography the mobile phase is a gas. The mobile phase, to which the mixture to be separated is added, transports the substance mixture through the separation column at a constant flow rate. Interactions occur between the mobile phase and the...

Providing field coverage is a key task in many sensor network applications. In certain scenarios, the sensor field may have coverage holes due to random initial deployment of sensors; thus, the desired level of coverage cannot be achieved. A hybrid wireless sensor network is a cost-effective solution to this problem, which is achieved by repositioning a portion of the mobile sensors in the netw...

We have investigated the effect of several common buffers (10-mM formic acid, 10-mM ammonium acetate, and 100-mM ammonium acetate) on the ionization of a series of model compounds that are amenable to negative atmospheric pressure chemical ionization to determine the extent of ionization quenching that can occur. In addition, we have compared the sensitivity of these standard mobile phases to a...

The use of atomically sized quantum systems as highly sensitive measuring devices represents an exciting and quickly growing research field. Here we explore the properties a quasiparticle formed by mobile impurity interacting with two-dimensional fermionic superfluid. energy is shown to be lowered superfluid pairing, this increases compressibility Fermi gas, thereby making it easier for perturb...

Modern mobile application processors are required to execute heavier workloads while the battery capacity is rarely increased. This trend leads need for a power model that can analyze consumed by CPU and GPU at run-time, which key components of processor in terms savings. We propose novel models based on phases using performance monitoring counters smartphones. Our phase-based employ combined p...

The onboarding phase of Free-to-Play mobile games, covering the first few minutes of play, typically sees a substantial retention rate among the players. It is therefore crucial to the success of these games that the onboarding phase promotes engagement to the widest degree possible. In this paper a set of heuristics for the design of onboarding phases in Free-to-Play mobile games is presented....

Objective(s):The present study reports the development and validation of a sensitive and rapid extraction method beside high performance liquid chromatographic method for the determination of crocetin in human serum. Materials and Methods:The HPLC method was carried out by using a C18 reversed-phase column and a mobile phase composed of methanol/water/acetic acid (85:14.5:0.5 v/v/v) at the flow...
