In this paper, we present the findings of a systematic literature review, consisting of quantitative and qualitative data, focusing on investigating Powder Metallurgy, as an alternative to traditional Sand Casting, by comparing certain characteristics of either process to synthesize the existing information of each method and to present an overview of manufactured materials.
Analysis and Results In this section, we analytically present the collected data.
Furthermore, it shows that journals are mostly classified as Q1/Q2, all indexed in Scopus with high levels of quality (SJR & H Index), so the validity of the data is guaranteed.
The strength of PM is the reduction of waste in its processes, thanks to the compaction in dust processing that allows the formation of loose metal for its use. [16].
If comparing a piece by traditional casting, the PM piece shows a reduction in porosity  [17].

Kullaa [2] used the missing data analysis.
The first set of data is called reference data set and is denoted by the index "0"
Detection Phase: The next data sets, with the same length as the reference data, are predicted with the AR coefficients obtained in the learning phase.
The first data set comprised signals from the healthy sensors.
By using autoregressive models for sensor fault detection, the measured time data is divided into small data sets of 6000 data points.

We derived a rainfall erosivity map based on data from 18 meteorological stations in and around the basin using the inverse distance weighting interpolation approach.
Methods There are many models for calculating R in different regions based on annual, monthly, or daily rainfall data.
The point estimates of rainfall erosivity generated using data from the 18 meteorological stations were interpolated by means of inverse distance weighting to produce a map of erosivity for the basin.
Results and Discussion Daily Rainfall Data The rainfall database consists of data provided by the National Meteorological Information Center of China from 5 meteorological stations within the Bailong River Basin and 13 meteorological stations around the study area.
Daily rainfall data provide more detailed information on precipitation variations than yearly or monthly data, and are therefore more useful for computing rainfall erosivity (Xin et al. 2011).

Instead, we used the data of rat #5 from box 4.
Data for habituation and saline was recorded for 40 minutes; data for amphetamine was recorded for 60 minutes to compensate for the time it takes for amphetamine to take effect.
Data for baseline and saline was recorded for five frequencies; data for amphetamine was recorded for seven frequencies to show that amphetamine lowers the threshold.
There might be some glitches in data collection: part of the data from mouse # 6 was missing; statistical tools (i.e.ANOVA ) have their own limitations ; the data collected were uneven etc.
To compensate for the uneven data in amphetamine condition, I omitted the data collected under 25Hz and 32Hz when using t-tests.

The solution suggested relies on a set of methods including techniques specific to medical imaging analysis and processing, graphical 3D representation of the anatomic model developed using experimental data and its manipulation for study-related purposes or for later processing.
The determination of the forces acting inside the stump-prosthesis system comprises two stages: (1) the reduction of the inner forces (muscle forces, tendon forces and contact forces between the bone surfaces) to a single force which is the resultant of all the inner forces; (2)the writing and analytical resolution of the dynamic balance equations for each stage of foot resting on the floor for the determination of parameters specific to the static and dynamic modeling of the anatomic stump-prosthesis system.

Following this, an experimental work was detailed relating to the use of ball nose end mill to machine hardened injection mould materials (up to 62 HRC).Surface roughness, surface topography and tool wear data were presented.
Through the data, it shows that each material has a small value of wear at 4-flute cutting tool and a bigger value of wear at 2-flute cutting tool, except for XW5 because of the tool Catastrophic Failure (CF).
Alloy addition, such as Cr to Fe–P based alloys will cause the increment in strength associated with the reduction in ductility [9].

The chip also has a shared L2 that only holds safe data.
All the data needed are acquired by L2 cache or memory accesses.
BOP calls them “checked data” [7].
So the one more cycle for load a data is essential.
