Full textIn avionics engineering, integration tests are crucials: they allow to ensure the right behavior of an airplane before his first flight, they are needed to the certification process and they allow non-regression testing for each new version of a system, of a software or of a hardware. The design of an integration test is expensive because it involves the implementation of the procedure, the configuration of tools of the bench and the setup of the interfaces of the system under test. With procedure written in natural language, the interpretation of statements of a test during the manual execution can lead to mistakes that are expensive to fix due to accurate actions needed to perform a statement. The formalization and the automation of those procedures allow testers team to focus on the implementation of new test cases. First of all, we introduce Domain Specific Language (DSL) and show how we use it to formalize tests procedures dedicated to a kind of system. Those languages should be able to be use by avionic testers which do not necessarily have programming skills. They allow test automation, while maintaining test intention in the test description. Then, we proposed a BDD (Behavior Driven Development) approach to validate the integration of systems thanks to behavioral scenarios describing the expected behavior of the airplane. Our contribution is a framework which orchestrate DSLs dedicated to integration test of avionic systems in an Agile vision. We named Domain Specific Test Languages (DSTL), languages used by expert testers. For each system (ATA ou Air Transport Association of America) corresponds a DSTL business. A first DSTL about the validation of airflow control systems has been developed as a proof of concept from existing procedures pseudo-formalized. The experimentation has been continued with IMA (Integrated Modular Avionic) calculators for which test procedures are written in natural language and thus are not automatable. From a corpus of procedures, we propose a first empirical process to identify sentence patterns composing the DSTL. The corpus provided is composed by ten procedures totaling 108 test chapters and 252 tests or subtests involving 3708 statements for a total of 250 Word pages. Make Agile integration tests in this context consist to propose a collaborative approach to formalize a DSTL and to integrate it in the orchestration framework to generate automatically the glu code

Full textToday’s web applications dedicated to trip planning are mainly limited to only one kind of transport service (urban transport, air transport, transport by rail and sea, etc. ). The user is then compelled to build manually his/her trip by combining available transport services. This querying can lead to process huge volumes of data, and can deliver massive responses, in which it is difficult to the user to distinguish the relevant answers from irrelevant ones. In this context, user preferences are considered in the process of retrieval of the best trip. In our case, user preferences are modelled by fuzzy bipolar conditions which associate essential preferences (very important preferences), and minor preferences (less important preferences), and expressed within a relational framework based on a bipolar relational algebra and a relational query language called bipolar SQLf. User preferences play the role of data screening, which we combine to a reasoning mechanism made of a description logic extended to m-ary relations and fuzzy bipolar conditions, so that only the most relevant data is targeted to evaluate user queries. We introduce in this thesis, a new approach for personalized querying of information systems dedicated to multimodal transport network, based on fuzzy bipolar preferences and ontologies. The objective is to provide users with means to combine automatically, in personalized and flexible way, several transport networks in order to plan their preferred trips. Preliminary results point out the potentialities of our approach in the development of new kind of personalized user services

Full textDespite the fact that multi-carrier signals amplification is pratically difficult due to their Gaussian-like distribution and the non-linear behaviour of power amplifiers, the orthogonal frequency division multiplexing (OFDM) modulation has been successfully brought in many communication standards for wired and wireless tranmsissions. However, the high peak-to-average power ratio (PAPR) of OFDM signals stands for the OFDM major drawback. Several strategies can be cited to manage the PAPR at transmitter side. However, most of them are computationally expensive and need a dedicated process at receiver relying on side information transmission. The deliberate amplitude clipping and filtering before amplification is an easy way to restrain PAPR at a desired level. If the out-of-band noise caused by clipping can be easilly discarded by filtering, the in-band distortion noise, also refered as clipping noise, must be mitigated at receiver side in order to restore the transmission performance. In this Thesis, we propose a wide review of both PAPR and clipping. We also give an analytical performance analysis of OFDM systems running under clipping constraint. Channel capacity and bit error rate are derived and conclusions are given. Afterwards, dedicated techniques mitigating clipping effects are studied. Clipping noise cancellation and decision aided reconstruction are especially reviewed. We also propose a complete comparison of these techniques and give an increased performance version of the first one. Finally, we propose a new scheme dealing with code word bits a posteriori probability enhancement. This soft decision is based on a suboptimal maximum likelihood (SML) detection using a limited neighbour signals to perform the transmitted code word detection. Actually, the receiver performance study shows that the algorithm can operate under severe clipping ratio constraint and is able to perform close to the non-clipped transmission case over both AWGN and frequencyselective channels

Full textThis thesis is for the development of future devices, systems and networks supporting the 5th Generation (5G) high-speed wireless internet. The demand for very high bit rate requires a sufficient large bandwidth, and therefore Millimeter-Wave (mm-wave) frequency band has a lot of interest. Several number of technologies will need to converge, co-exist and interoperate, and most importantly, cooperate, if this vision is to be efficiently and cost-effectively realized. The main concept within this next 5G is the integration of optical fiber networks and radio networks through Radio-over-Fiber (RoF) technology at mm-wave frequencies, to provide high-bandwidth front/backhaul services and enable scalable and manageable networks without a highly complex interface structure and multiple overlaid protocols.In this thesis, the mm-wave RoF communication systems are theoretically studied and experimentally demonstrated to investigate the system impairments. The work presented in this thesis is focused on optical noise represented by phase and intensity noise induced by optical source and chromatic dispersion introduced by optical fiber. The optical noise is analyzed and measured for different optical generation techniques. Two different down-conversion stages, mixer and envelope detector, are applied for signal processing and to decorrelate phase and intensity noise. We would like to highlight that this study and the model can be applicable toany kind of optical heterodyne generation system and any frequency range. The correlation among optical modes in optical frequency comb is examined to show the impact of chromatic dispersion. This thesis also exhibits the mm-wave power distribution over fiber span and how the chromatic dispersion effect on the RoF network is modified by varying dispersion parameters. Then, this thesis demonstrates how the optical phase decorrelation induced by chromatic dispersion results in mode partition noise at mm-wave RoF communication networks.When transmitting some types of data over the system, the results demonstrate the impact of optical noise and chromatic dispersion on the signal quality. The simulation results are presented and are in very good agreement with experimental results. The error vector magnitudethrough online process shows the impact of the system impairments on the system performance. The data rate and system evolution are compliance with communication standards at mm-wave

Full textDuring my thesis entitled "Design and development of tools dedicated to reflexive systems. Application to car maneuvers recognition. "I developed an inference engine, called Reflexive System Inference Engine (RSIE), based on a hybrid between RETE networks filter method to combine performance and flexibility of application. RSIE structure allows it to create systems which not only interact with their environment but also with their own knowledge allowing them to self-edit according to solve problems, known as reflexive systems. I applied this engine to CASSICE project (Caractérisation Symbolique des SItuations de ConduitE) and more particularly to the rule-based system IDRES. IDRES rules have been translated into RSIE formalism and the adding a of knowledge management metarules to implement a time t have improved IDRES performances in terms of speed of execution and in terms of resources occupation. By its nature, RSIE can be applied to other areas and this is part of my perspectives
