Impact of Fruit Ripeness on Physicochemical Properties and Convective Drying Characteristics of Kent Mango (Mangifera indica L. cv.'Kent')
D. BATHIEBO
Impact of ripeness on drying characteristics of mango was studied by considering different zones on the fruit. For each zone, ripeness was estimated by total soluble solids/acidity ratio, colour and texture of fruit flesh. For each state of ripeness, drying curves and time-temperature curves were established both in forced and natural convecti(...)

Transformation of any Adding Signal Technique in Tone Reservation Technique for PAPR Mitigation thanks to Frequency Domain Filtering
Désiré GUEL, Jacques PALICOT
Orthogonal Frequency Division Multiplexing (OFDM) suffers from a high Peak-to-Average Power Ratio (PAPR). Tone Reservation (TR) is a popular PAPR reduction technique that uses a set of reserved subcarriers to carry the peak reducing signal. The major advantages of TR technique include no transmission performance degradation, no transmission of(...)

Bridging the gap between legacy services and web services
T. BISSYANDE
Web Services is an increasingly used instantiation of Service-Oriented Architectures (SOA) that relies on standard Internet protocols to produce services that are highly interoperable. Other types of services, relying on legacy application layer protocols, however, cannot be composed directly. A promising solution is to implement wrappers to t(...)

Improving system testability and testing with microarchitectures
Aminata Sabane
Testing is essential to ensure software reliability and dependability. however, testing activities are very expensive and complex. Micro architectures, such as design patterns and anti-patterns, widely exist in object oriented systems and are recognized as influencing many software quality attributes. Our goal is to identify their impact on sy(...)

Tone reservation technique based on geometric method for orthogonal frequency division multiplexing peak to- average power ratio reduction
Désiré Guel, Jacques Palicot, Yves Louet
Orthogonal frequency division multiplexing (OFDM), has recently attracted considerable attention because of its features to combat delay spread or frequency selective fading of wireless or wireline channels. One of the major drawbacks of OFDM is the peak-to-average power ratio (PAPR) which leads to an inefficient use of high power amplifiers ((...)

Impact of land-use type and bark-and leaf-harvesting on population structure and fruit production of the baobab tree (Adansonia digitata L.) in a semi-arid savanna,...
A. THIOMBIANO
Non-timber forest products (NTFPs) strongly contribute to livelihood security in the semi-arid tropics. There is increasing concern about the population status of NTFP-providing trees and therefore a need for their sustainable use. Thus, this study examines the impact of land-use type on the multipurpose baobab tree (Adansonia digitata L.) in(...)

Composition and Antimicrobial Activities of Lippia multiflora Moldenke, Mentha x piperita L. and Ocimum basilicum L. Essential Oils and Their Major Monoterpene Alcohols Alone and in Combination
Imaël Henri Nestor Bassolé , Aline Lamien-Meda , Balé Bayala , Souleymane Tirogo , Chlodwig Franz , Johannes Novak , Roger Charles Nebié and Mamoudou Hama Dicko
Essential oils from leaves of Lippia multiflora, Mentha x piperita and Ocimum basilicum from Burkina Faso were analysed by GC–FID and GC–MS. Major components were p-cymene, thymol, β-caryophyllene, carvacrol and carvone for L. multiflora, menthol and iso-menthone for M. x piperita and, linalool and eugenol for O. basilicum. The(...)
