International Oil Market (IOM) and economic inflation are interesting financial topics that have attracted the attention of researchers over the last years. The dataset for both of them is chaos in behavior, irregular, nonlinear and dynamic variation. The aim of this thesis is to design system have the ability to forecast the complex and irregular behavior of oil price and inflation rate then find out the pass-through degree of oil prices into inflation rate. The proposed system has given great interest in generating technical indicators adapted to oil prices and inflation rates for different periods. The efficiency of the model has achieved by Regression Relief Features Selection method employed to select attributes with the highest degree of significance. Additionally, A developed forecasting model is proposed which is called Multi-pass Support Vector Regression (MSVR) that express the errors in forecasting past and current periods to forecast the future. The system is applied on the two IOMs (WTI and Brent) datasets with different time periods (daily and monthly), in addition to one dataset for inflation rate more precisely is the monthly inflation rate of United States(US). In order to evaluate the forecasting model; Mean Absolute Error (MAE) and Root Mean Square Error (RMSE) are employed for this purpose. The best MAE and RMSE values of the proposed model for current time have reached to 0.0001 and 0.0003 in case of inflation rate, respectively, while 0.0279 and 0.0369 for oil pries, respectively. The best enhancement future accuracy value of the proposed model have been reached to 96.86% and 99.99% for crude oil and inflation rate, respectively. As well as, a comparison with other common regression methods (traditional Sequential Minimal Optimization (SMO) and Multiple Layer Perceptron (MLP)), the results show that the performance of the proposed system is better for all evaluation parameters. Finally, Fuzzy Correlation Model (FCM) is used to find the relationship between oil price and inflation rate. Hence, the experimental results of FCM indicate a clear relationship between oil prices and inflation rate more than 50 %.While, the remaining percentage may reflect the presence of other factors that have an effect on inflation rate in addition to the oil price.

Self-compacting concrete depends on the amount of mortar in concrete mix for giving enough flow to fill the voids without using mechanical vibration. Increasing the amount of mortar makes drying and plastic shrinkage increase with some changes in hardened and thermal properties of concrete. The main goal of this study is the use of modified admixture which works for decreasing the drying and plastic shrinkage and increasing concrete strength. Also, this study evaluates the thermal and hardened properties of concrete and their effect on the properties of rigid pavement. This research aims to investigate the properties of SCC produced by locally available materials and to study the effect of the addition of fibers, Sika Latex and the reduction of (w/p). Four mixes are used: reference mix (RM) is a self-compacting concrete (SCC) without modified admixture, in the second mix the (W/P) is reduced from (0.35) to (0.27), the third mix 5% of sika latex is added and in the fourth mix 1% of steel fibers is added. To determine self-compatibility features for those mixes, different test methods are adopted in this research such as slump-flow, T50 slump-flow, L-box, and sieve segregation resistance. The studied hardened properties are compressive strength, splitting tensile strength, modulus of rupture and static modulus of elasticity. The studied thermal properties are coefficient of thermal expansion (CTE), thermal conductivity (K) and specific heat (C). The results show that the slump-flow range is from (555 to 630) mm, T50 slump flow range is from (3.46 to 6.23) Sec., the blocking ratio Abstract II(H2/H1) of L-box range is from (0.65 to 0.89) and the sieve segregation resistance range is from (1to 4) %. Self-compacting concrete with steel fibers (SCC-SF) shows the highest coefficient of thermal expansion (CTE) at (7, 28) days with increasing range from (3 to 16) % compared with the other mixes. Also, SCC-SF showed the highest thermal conductivity (K) at (7, 28, 56) days, this increase was from (3 to 22) % when it was compared with the other mixes. SCC-SF showed the highest modulus of rupture (MR) at (7, 28, 56) days, this increase was from (28 to 64) % when it was compared with the other mixes. Three statistical models were developed to combine (MR) and (CTE) with W/P, additive percentage and age. The decrease in slab thickness of rigid pavement was (21, 5 and 40)% for SCC-WR, SCC-SL and SCC-SF respectively when they were compared with the reference mix. The increase in joints spacing was (25, 9.4, 63.4) % for SCC-WR, SCC-SL and SCC-SF respectively when they were compared with the reference mix. Finally the results showed that the SCC-SF is more adopted for rigid pavement construction

La diminution significative de la fertilité bovine et les exigences croissantes des éleveurs ont des vaches inséminées (TC) pour l’un ou l’autre des protocoles utilisés. De bonnes performances reproductives globales ont été obtenues (TRC= 63.26% ; TG=49.38% ; TC= 78.06% ;P<0.05), ce qui donnaient des résultats spécifiques à chaque catégorie de traitement utilisée:Traitements à base de PGF2α seule ou associée à la GnRH: Cent cinq (105) vaches et génisses étaient réparties en trois lots (N=35) représentées comme suit. Un lot à base de deux injections dePGF2α (lot 1) et deux lots associés à la GnRH (« GPG » lot 2 et « GP » : lot3). Cette catégorie de traitement a enregistré un TRC global de 54% en faveur du lot 1 (74%) par rapport aux lots 2 et 3(49% vs 40% ; P= 0.431). Par ailleurs, un faible taux global de gestation (38%) a été relevé ce qui correspondait à (54.42%, 31,4% et 29% ; P= 0.00023) respectivement pour les lots 1, 2 et 3.Cependant, un meilleur taux global de conception a été recensé (69.72%) avec des taux correspondants respectivement aux lots 1, 2 et 3 (73%, 64,7% et 71,4% ; P= 0.387).Traitements à base de t TC= 82.65% ; P= 0.00064). De bons TRC ont été enregistrés pour les lots 4 et 7 et à un degré moindre pour les lots 5 et 6 (80,0% et 74.28% vs 60% et 66% ; p=0.01). Des TG à 30 jours étaient plus ou moins élevés (60%) pour les deux lots utilisant les implants (lots 6 et 7)par rapport aux lots 4 et 5 (57,1% et 54.28% ; P= 0.819). Par ailleurs, de meilleurs TC (71,42%,90,47%, 91,30% et 80,76% ; P= 0.043) ont été recensés pour les quatre lots.Les meilleures performances enregistrées sont principalement observées dans les protocoles à base . Les prim'Holstein et les primipares sont les moins fertiles comparativement améliorer de plus les performances reproductives. () The significant decrease in bovine fertility and the increasing demands of breeders have made it essential to regularly monitor reproduction to identify and resolve potential problems affecting reproduction at an early stage. The objective of this study was to compare the fertility with estrus induced by seven (07) heat synchronization protocols based on GnRH, of synchronized cows confirmed by ultrasound at 30 days post-insemination (Pr) and the conception rate of inseminated cows (Cr) for one or the other of the protocols used. Good overall reproductive performance was obtained (HRr= 63.26%; Pr= 49.38%; Cr= 78.06%; P <0.05), which gave specific results for each category of is used: Treatments based on PGF2αalone or associated with GnRH: One hundred and five cows and heifers(105)were divided into three groups(N = 35) represented as follows. A group 1based on two injections of PGF2αand two with GnRH (“GPG” and “GP”:). This treatment category recorded an overall CRR of 54% in favor ofgroup1 (74%) compared to groups2 and 3 (49% vs40%; P = 0.431). In addition, a low overall pregnancy rate (38%) was noted which corresponded to (54.42%, 31.4% and 29%; P= 0.00023) respectively for lots 1, 2 and 3. However, a better overall conception rate was identified (69.72%) with rates corresponding to respectively groups 1, 2 and 3 (73%, 64.7% and 71.4%; P= 0.387). Progestin-Based Treatments: One hundred and forty cows and heifers (140) were divided into four lots (N = 35) represented as follows. Group 4 “CIDR + GPG”, group 5 “PRID + GP”, group 6 “CRESTARSO® 300UI” and group7 “CRESTAR SO® 500 UI”. Better overall reproductive performance was noted in this treatment category (CRT = 70.07%; TG = 57.85% and TC = 82.65%; P <0.00064). Good HRrwere recorded for groups4 and 7 and to a lesser degree for lots 5 and 6 (80.0% and 74.28% vs.60% and 66%; P= 0.00023). Prat 30 days post-insemination were more or less (60%) for the two lots using the implants (lots 6 and7) compared to lots 4 and 5 (57.1% and 54.28%; P = 0.819). In addition, better Cr(71.42%, 90.47%, 91.30% and 80.76%; P = 0.043) were identified for the four groups. The best performances recorded are mainly observed in the required with respective corrective actions. A large-scale study comparing other protocols with possible to the dose and timing of hormone injection would be relevant to reproductive performance.
