This work designs a two-level strategy at signalized intersections for preventing incident-based urban traffic congestion by adopting additional traffic warning lights. The first-level one is a ban signal strategy that is used to stop the traffic flow driving toward some directions, and the second-level one is a warning signal strategy that gives traffic flow a recommendation of not driving to some...
An efficient method was developed to compute the pressure field induced on the seafloor by a ship performing maneuvers such as acceleration, deceleration, and turning. Linear, potential flow theory with transient, finite-depth Green function is used to formulate the solution for the velocity potential. To reduce run time, thin-ship approximation is made, and the Green function is evaluated using Chebyshev...
Intelligent Transportation System (ITS) is integral towards envisioning a truly mobile and digital India. While existing solutions like smart vehicles and autonomous driving are inapplicable for Indian cities, transport surveys in India have provided offline solutions through GPS data. Without analytical formulations, they are prone to failure in ever-changing Indian urban landscape. This paper addresses...
In this work we recover the Discrete Hill's equation introduced by Chulaevsky in 1989 [11] and give it a graphical interpretation of parametric stability [12] i.e. discrete Arnold tongues. We give the nonoscillatory criteria for discrete Hill's equation and proved that all the nonoscillatory solution of the discrete Hill's equation fall into the 0-th Arnold tongue.
This paper present the analysis and design of a converter Boost with low current stress, the proposed topology is based in the integration of multi-phase and multi-stage scheme. The design methodology enable obtain a high CD voltage with low ripple in voltage and, for validate this converter is presented the design for output power of 100W, the simulation results obtain validated the propose for design...
This article presents the simulation and harmonic analysis of a charging station model developed in “Modeling and protection of electric vehicle charging station”, which was adapted with the electrical parameters of the distribution system of Cuenca city, with The purpose of quantifying the amount of harmonics that this type of stations can produce in the network. The simulation resulted, that the...
In this paper we present a case study emphasizing the proposal of a telecare system which might be implemented in the first attention level belonging to health centers of Periurban zones of Lima city. Concretely, the system relies entirely in an algorithm which is based on a mathematical scheme that models the behavior of the glucose in type 2 diabetes patients under episodes of binge eating disorder...
The liberalization of power markets has led to changes in the electricity pricing mechanism. Under this new paradigm, the introduction of competition in the generation segment entails a price determination according to an economic dispatch of generating units. However, transmission constraints usually imply a subsequent alteration of the supply costs, above those purely due to the power production...
In this work is reported a brief summary of considerations for the design of a basic readout CMOS integrated system applied for the conditioning of small signals taken from a floating-gate based CMOS-MEMS capacitive structure intended for inertial measurement. Both the electromechanical structure and the readout circuit (consisting in a variable capacitor coupled to the gate of a MOSFET and a conventional...
Safety and non-safety application services require a guarantee of network performance, mostly in terms of throughput and packet collision. The current radio propagation path loss models use mean additional attenuation sophisticated fading model and do not consider the obstacle caused due to obstacles of vehicles in LOS of transmitting and receiving vehicles. This affects the attenuation signal at...
The research presented here is introducing a modelling approach which investigates the influence of different runoff parameters that are used in the modelling process to achieve a suitable representation of the urban catchments runoff. The aim of this research is to analyse the calibration of a hydrological model in the area of Ølsted, Denmark. Quantitative data such as rainfall, water level and flow...
In recent years, semantics-based crossover operators have attracted attention for efficient search in Genetic Programming (GP). Geometric Semantic Genetic Programming (GSGP) is one of the methods, in which a convex combination of two parents is used for creating an offspring. We have previously proposed an improved GSGP, Deterministic GSGP. In Deterministic GSGP, the convex combination is relaxed...
Developing a driving cycle in according with the actual road conditions is instrumental for the matching of power system design, fuel economy and emissions assessment. This paper used GPS to collect the actual operation of taxi in Harbin urban and divided into four model events: acceleration, deceleration, cruising and idle. The model events with similar mean of velocity and average acceleration are...
It's well known that the duration of the engineering programs in Latin American countries like Peru are of order of 5 years, roughly. Commonly, the target of the fifth year of program is to carry out activities of thesis and capstone projects. Clearly these activities would demand that the student can exhibit skills and a certain level of maturity which might be crucial for a successful completion...
The world has recently witnessed a great tendency towards rapid urban development. This has been accompanied by an increase in the population and a development in the uses of the land, which changes the reality of transport and increases its problems over time. The city of Mansour suffers from traffic jams in certain parts of its road network due to the increase in population and the shift in the...
Due to growing concerns for pollution caused by gasoline powered vehicles, countries around the globe are becoming increasingly aware of a promising means of transportation—plug-in electric vehicles (PEVs). Despite their incomparable advantages over traditional vehicles in emission reduction and energy saving, PEVs impose significant pressure on the existing power systems. Therefore, understanding...
Searching for a parking spot wastes time and energy, and becomes more prevalent with electric vehicles. This waste can be reduced by assigning drivers to parking lots based on their destination and arrival time. In such a system, drivers could request a parking spot in advance and be alerted (e.g., via their phone or vehicle) of their assignment to a specific parking lot or available spot. In this...
The mathematical model and determined the quantity of lighting on the plane of a sloping roof, from the firmament with a standard of the brightness distribution in the annual cycle for the cities of Nalchik and Moscow. According to the analysis method is developed to improve the technical and economic efficiency of an obliquely positioned light devices.
Recently, UAVs (Unmanned Aerial Vehicles) gain a wider acceptance from many disciplines. One major application is for monitoring and mapping. Flying beyond eye sight autonomously and collecting data over large areas are their obvious advantages. To support a large scale urban city mapping, we have developed a UAV system which can carry a compact digital camera as well as a navigational grade of a...
In residential building sector, the provision of clean water is the one of primary need. The water pump used to do that matter. The technology for renewable energy source, i.e. Solar Water Pumping System (SWPS) will help the society in this sector to decrease the electricity consumption for providing clean water. The SWPS converts the solar energy into electricity. Then, the electricity used to activate...
