Design of In-Flight Instrumentation to Characterize a Hybrid Thruster

The NASA Undergraduate Student Instrument Project (USIP) is a program with the goal to provide hands-on flight project experience to undergraduate programs, and to fly new technology in space to improve Technology Readiness Level (TRL)

Italian hybrid fire prevention code

Fire safety of residential buildings and activities subjected to fire inspection is a difficult task, especially when the safety targets have to be adopted in built buildings or in activities that are going to be modified into more complex ones. Generally, these circumstances show more constraints and it could be difficult to achieve an acceptable level of fire residual risk by prescriptive based fireregulations. Therefore, the Italian National Fire Rescue and Service in charge for fire safety, in August 2015 issued a new Fire Prevention Code whose design methodology is more oriented to fire performance based design rather than prescriptive fire codes. The flexibility of this new fire design methodology offers a very complex tool to experts in order to design fire safety measures and strategies of buildings and activities subjected to fire inspection. The present paper aims tohighlig hts the contents and the fire safety strategy design methodology of the new Italian Fire Prevention Code

On Robust Stability of Limit Cycles for Hybrid Systems with Multiple Jumps

In this paper, we address stability and robustness properties of hybrid limit cycles for a class of hybrid systems with multiple jumps in one period. The main results entail equivalent characterizations of stability of hybrid limit cycles for hybrid systems. The hybrid limit cycles may have multiple jumps in one period and the jumps are allowed to occur on sets. Conditions guaranteeing robustness of hybrid limit cycles are also presented

RELIANCE ATTITUDES OF FARMERS IN CHOOSING HYBRID AND NON-HYBRID SEEDS IN CORN FARMING (CASE STUDY IN THE DISTRICT OF PURI DISTRICT. MOJOKERTO, EAST JAVA)

The purpose of this study are: 1). Analyzed the attitude of the farmers trust in choosing Hybrid and Non-Hybrid seeds on corn farming. 2). Knowing the superior attributes of corn seed hybrid and non-hybrid is an option for farmers. 3). Analyzed the economic feasibility of farming of corn hybrid and non hybrid. The research method used analysis of Fishbein Multiattribute attitude models to detect first and secondary objectiveness, while the third objective economic analysis of farming used by an analysis of cost and revenue balance (Return and Cost Ratio). The finding are show 1). Farmers who consider the most important attributes in selecting seed corn hybrid (P-21), (Bisi-2) is the Production, Growing Power, Brand, Efficiency uses Fertilizer, Seed Availability and Seed Price. In the other side Resistant toward drought attributes deemed most farmers less important than other attributes. The most important attributes of corn seed non-hybrid (Local) is Seed Price, Growing Power, Production, Brand, Resistant toward drought and Efficiency uses Fertilizer. While Seed Availability attributes deemed most farmers less important than other attributes. 2). Superior attributes selected by farmers on farms using corn seed hybrid (P-21), (Bisi-2) are production, While that use corn seed non hybrid (local) are seed price.. 3). Corn farming that use seed hybrid (P-21) and (Bisi-2), more efficient from seed non hybrid (local), and economical beneficial with feasible to carried on

On Statistical Properties of Jizba-Arimitsu Hybrid Entropy

Jizba-Arimitsu entropy (also called hybrid entropy) combines axiomatics of R\'enyi and Tsallis entropy. It has many common properties with them, on the other hand, some aspects as e.g., MaxEnt distributions, are completely different from the former two entropies. In this paper, we demonstrate the statistical properties of hybrid entropy, including the definition of hybrid entropy for continuous distributions, its relation to discrete entropy and calculation of hybrid entropy for some well-known distributions. Additionally, definition of hybrid divergence and its connection to Fisher metric is also discussed. Interestingly, the main properties of continuous hybrid entropy and hybrid divergence are completely different from measures based on R\'enyi and Tsallis entropy. This motivates us to introduce average hybrid entropy, which can be understood as an average between Tsallis and R\'enyi entropy

Hybrid Geometric Reduction of Hybrid Systems

This paper presents a unifying framework in which to carry out the hybrid geometric reduction of hybrid systems, generalizing classical reduction to a hybrid setting

Equivalence of switching linear systems by bisimulation

A general notion of hybrid bisimulation is proposed for the class of switching linear systems. Connections between the notions of bisimulation-based equivalence, state-space equivalence, algebraic and input–output equivalence are investigated. An algebraic characterization of hybrid bisimulation and an algorithmic procedure converging in a finite number of steps to the maximal hybrid bisimulation are derived. Hybrid state space reduction is performed by hybrid bisimulation between the hybrid system and itself. By specializing the results obtained on bisimulation, also characterizations of simulation and abstraction are derived. Connections between observability, bisimulation-based reduction and simulation-based abstraction are studied.\ud \u
