The problem of missing of some of sample observations is one of the main problems that face researcher during the statistical analysis , the main problem of missing data are as follows damage , negligence, death and morbidity as in the case of clinical studies
The presence of such a problem within the data may influence on the analysis and accordingly it may lead to misleading conclusions despite the fact that the wavelet estimations are of high efficiency in estimating the regression function , but it may be influenced by the problem of missing data , in addition to the impact of the problem of miss of accuracy estimation it is not possible to apply these methods because of the miss of one of its conditions which is dyadic sample size .
According to the great impact stem from that problem , many researchers who devoted their study to process this problem by using traditional methods in processing missing data , where as the researcher used imputation methods more efficient and effective to process the missing data as a primary stage so that these data will be ready and available to wavelet application, as a result simulation experiment proved that the suggested methods (DRPW) are more efficient and superior to other methods , this paper also includes the auto correction of boundaries problem by using polynomial models , and using different threshold values in wavelet estimations , SINCE the suitable choice of this value is decisive accuracy of these estimations

Local anesthesia is a temporary loss of sensation including the sense of pain in a part of the body and it happens by injection of local anesthetic agent without loss of consciousness. In this research we study this problem to evaluate the efficacy of local anesthesia which is given to patient in case of toothache and dental caries through the using of control chart such as mean chart, dispersion chart, cusum chart In addition to use (xand Moving Rang-chart).
We explain the effect of the age and gender in withstanding the pain due to injecting the patient with this type of local anesthesia in addition to the suitable time for waiting period till the local anesthesia start to be effective. The sample include (80) patients injected with local anesthesia (Lidocaine with adrenaline) which is the most used local anesthesia, safe and effective if it is used within its regulations.
The result is that: there is no relation between the age and the waiting period needed to be waited by patient in addition to that the gender has no effect on waiting period.
But generally, males are more withstanding the pain than female and the adult &old patients are the most withstanding and understanding to the pain than children.

Start of the Iraq critical period reflected in the growing demand for agricultural and food products as well as higher food prices in international markets and reduced the relative importance of the agricultural sector in the economic structure of Iraq has resulted in this topic worsening food shortages in Iraq and the increased reliance on external sources to feed the population and declining per capita Iraqi agricultural output as well as the deterioration of the proportion of agriculture in the area of GDP, has led to the deterioration of the value of agricultural output to decline in per capita GDP
And continued the country suffers from food gap which is growing ever since the beginning of the nineties of the past century, has reached the peak of its greatness in the moment, and Pat finance food import heavy burden on the financial budgets of the state and drains a significant number of national income is moving towards overseas markets to meet the need for deepening food part .As a result, Iraq is one of the world's most Toreda of food at present, since the deterioration of self-sufficiency rates are a threat to food security, which is an essential component of national security.

Administration seeks in economic units to achieve its strategic goals through the preparation and implementation of plans to meet the competitors markets - domestic and foreign and to meet the needs of customers of products and services at competitive prices and specifications, as well as to achieve added value for stakeholders. So, some of these economic units resort to follow a variety of methods to cope with the pressures they face, and led to reduce some of the activities or reduce costs or change prices and expansion in the provision of after-sales services; however, those methods alone may not solve all problems.
A business organizations achieve competitive advantage - whether to introduce new products or reduce the costs of existing products - using value analysis methods and the value chain to reach the target cost and selling at bargain prices, and that a strategic objective. But achieving this goal may face the occurrence of some practical problems related to take some decisions, Exclude of some activities that do not add value - of the product or economic unit or reduce some of the costs, to be studied and analyzed their effects on products and activities of the organization, so was the drafting of the research problem follows by asking:
Is that the use of value analysis and value chain improves the value of the product and reduces costs which improves the competitive position of economic unity?
The most important results is the style of value analysis and value chain as a foundation stone to gain a competitive advantage and maintain, where the style of value analysis works to improve or abolish the functions of the product while the value chain works to reassemble the economic activities of the unit in a manner that supports activities that add value and excludes activities that do not add value in accordance with the method allows an understanding of the causes of the costs, and sources of discrimination

A simple yet sensitive high performance liquid chromatography method was developed and validated for the determination of paracetamol (PCM) content in different tablets dosage form. The mobile phase consisted of a mixture of methanol: water (80:20 v/v). The HPLC analysis was performed at a flow rate of 1 mL/min using a Thermo Synchronise C18 (150 × 4.6mm, 5μM) and an UV detection wavelength of 254 nm was used. The method was validated for selectivity, linearity, precision, accuracy, limit of quantification (LOQ), limit of detection (LOD), robustness and solution stability. The calibration curve was linear over a concentration range of 20 to 70 µg/mL (r2 = 0.9997) with LOD and LOQ of 0.01 and 0.03 μg/mL, respectively. The retention time for paracetamol was 1.5 min. The relative standard deviation percent (%RSD) and the relative error percent (%RE) of calibration curve were between 0.03-1.03% and 0.05-1.11%, respectively. The intra- and inter-day precision and accuracy were between 0.02-1.55% and 0.10-0.78%, respectively. In addition, the %RSD of short term stability and the method robustness were between 0.4-1.20% and 0.09-1.43%, respectively. All results followed the ICH guideline Q2 (R1) which indicates the precision and accuracy of the developed method. The method was successfully applied to assess PCM content in different marketed tablets in Iraq.

The heat exchanger systems have highly nonlinear features between its variables and time delay. In addition, the parameters of them change constantly during operation. Therefore, the heat exchangers need nonlinear robust controller for obtaining required outlet temperature under all operating conditions.
In this paper, a robust nonlinear neural PID (NLNPID) controller is proposed for temperature control of double-pipe heat exchanger. Particle swarm optimization (PSO) technique is used to determine on line auto tuning the optimal parameters of proportional-integral-derivative (PID) controller. Mathematical model of heat exchanger takes into account the changes in the density, thermal conductivity, viscosity, specific heat and convection heat transfer coefficient of the fluid which are resulting from changing in temperatures and the velocities with classical PID control. Simulations results show that the performance of the NLNPID controller produces good responses features and give desired outlet temperature under all operating conditions without over shoot and fluctuating.

This paper presents a design and simulation of proposed MASH (Multi-stAge noiSe sHaping) modulator which can be used for GSM applications. MASH technique is chosen for GSM system, since low settling time, spurious level and phase noise can be obtained by using this technique. The phase noise obtained with this modulator is 30 dB if compared with other modulating techniques. Matlab (R2013a) is used for simulation of 3rd order, 32-bit digital MASH modulator.

The aims of this in vitro study is to evaluate and compare compressive strength of newer nanocomposites (FiltekZ350, Ceram X Mono,Herculite XRV Ultra) with microhybrid (FiltekZ250) and to assess difference in compressive strength of newer nanocomposites.
Materials and Methods: Forty specimens of composite were made using plastic mold measuring 5mm x 5mm and were grouped with ten specimens in each ,Group I: Filtek Z 250, Group II: Filtek Z 350, Group III: Herculite XRV Ultra, Group IV: Ceram X Mono. Composite resins are placed in cylindrical plastic mold and covered with celluloid strip and were cured by light curing device. Compressive strength was recorded using universal testing machine. Results are statistically analyzed using one way ANOVA and LSD test.
Results: Nanocomposites have better compressive strength value than microhybrid composite but they are not significantly different and not all of nanocomposites used were higher than microcomposite.
Conclusion: Nanocomposites (Filtek Z 350) have comparable compressive strength with microhybrid composite resins (Filtek Z 250) in which using both of them is indicated in anterior and also posterior areas where the functional loading is higher and need super mechanical properties to withstand these forces. While other nanocomposite groups (Herculite XRV Ultra, Ceram X Mono) used in this study have lower compressive strength than others groups.

Facial recognition systems are computer-based security systems that are able to automatically detect and identify human faces. Biometric systems Though Iris Scan, Finger Print and Hand Geometry biometric system have proven to be effective, it requires cooperation from the person being scanned, the last are critical in a wide range of applications such as banking system, E-commerce, smart cards, and access control to secure system, face recognition system is one of the most reliable biometric systems, which is used for identifying persons. The proposed system describes a method for human recognition based on eigenface, correlation distance, training set of images, and a threshold which it used to classify the images and accept the detection of images that have a minimum value below the threshold. And noise removal used to enhance the performance of the original PCA algorithm in the recognition process; it gives more accurate results in recognition. This study aim is to design a face image recognition system, which is capable of identifying a face with high level of accuracy. Therefore, this system can be applied to a wide range of many applications.
