Energy data science is the best solution to protect consumers against the electricity market's inefficiencies.
Price prediction mechanisms in the field of energy data science (EDS) are solving this issue.
EDS has become possible through both a vast increase in available market data and an ability of our Energy Data Scientists to interpret that data to produce pricing opportunities.
These classification models allow our Energy Data Scientists to identify the underlying state of the grid.

Results: There were no differences in patient age, fracture type, BMD, ASA, hospital stay and reduction quality.
Patient data also included operative time, postoperative complications, number of blood transfusions, level of pain (assessed by a visual analog scale, on the fifth postoperative day) and length of hospital stay.
In Group A, the reduction over time in the femoral neck-shaft angle was 6 ± 8, while in Group B, the reduction was 2 ± 1 (p < 0.002).
The reduction was well-maintained

Another event is the so-called voltage reductions.
One cycle of acquired data is used to compute the RMS voltage.
The filter was employed to extract data for event characterization while the S-Transform was needed for perturbation detection.
The fuzzy system was employed to analyze the data for power quality characterization.
Numerous real-life applications use digital data today.

To start, the capacitor cost, available capacitor, number of buses, load data, bus data, line data and other variables will be defined first as shown in Fig. 2.
In addition, each particle includes two data which are the capacitor size and bus number, and will be exported to the OpenDSS engine for power flow solution.
The loads data, Bus data, Line data and all information about this case study can be found in [10].
Fig. 3 (b) indicates the losses for each bus which there is losses reduction after the optimum capacitor installation.
It shows the nature of cost reduction during the NFE and number of iterations.

With the researches going further, Transition metal macrocycles have been of great interest in catalytically reduced oxygen reduction.
Therefore, seeking novel catalytic materials has become an effort to optimize the oxygen reduction occurring on the cathode surface.
Bio-films developing on the cathode surface by some microorganisms have proved to be feasible to play a role in catalyzing reduction reactions.

By dealing with the ultimate bearing capacity test on 12 short columns of separation CFST which are subjected to the eccentric compression, this paper has studied on the mechanical properties of non-separation side compression CFST, revealed the influence of separation ratio and the eccentricity ratio to mechanical properties, and provided basic research data for further CFST study in the future.
The basic data of the CFST are shown in table 1.

Eqs. 1 allows for the correction of the gas yield data, which is presented at room temperature conditions typically, to the decomposition temperature instead [7]. ∅= ∅STP × VcVroom= ∅STP ×TcTroom (1) Where Vroom, Vc, Troom, and Tc refer to gas volume at room, crystallisation, absolute room, and absolute crystallisation temperatures.
MIPAR image analysis software was used for the extraction of transient height change data.
Due to the complexity of the images, colour segmentation tools were found to be the most useful for extracting the data from the image, establishing the white shades in the foam to separate them from the other background colours of the image.
The frames from each experiment were imported into MIPAR to extract the transient sample height data.
An optimal value exists though, as concentrations above 3wt% only produce a small reduction in foam density.

The supercharged model was calibrated by using the original experimental data.
Introduction As the stringent regulatory requirements, energy saving and emission reduction are the goal of today's social development.
The supercharged model was calibrated by using the original experimental data that ensure errors ranking in 5%.
Two-stage turbocharging system is a useful way of energy saving and emission reduction.

Next, LLE (Locally Linear Embedding) algorithm is adopted to reduce the data dimension.
Its target is to find low-dimensional manifold structure embedded in high-dimensional data and give an effective low-dimensional representation.
A significant characteristic of LLE is to keep the locality of data, so it can be used for cluster analysis and pattern recognition.
Then if without dimensionality reduction on data, the classification results obtained by different kernel functions are shown in table 1.
Figure 3.Recognition rates with different dimensions However, high dimensions will increase the difficulty of data processing, so feature data should be optimized before SVM.

Study on Debenzylation of Pentabenzylpentaza[3,3,3]Propellane Yahan Xue1,a*, Jiarong Li1,b, Lizhu Zhang1,c, Guangwei Zhou1,d and Zhibin Xu1,e 1Beijing Institute of Technology, China axueyh666@163.com, bjrli@bit.edu.cn, czlzfx8@126.com, d2120161266@bit.edu.cn, ezbxu@bit.edu.cn Keyword: Catalyst, Aza-propellanes, reduction, debenzylation Abstract.
Based on the theoretical study of some polynitro-polyaza[3.3.3]propellane molecules, the debenzylation of pentabenzyl-pentaaza[3.3.3]propellane was studied by simple raw materials and convenient conversion. 2 Experimental 2.1 General Methods and Material Generally, the debenzylation method adopts the reduction method, and the reduction debenzylation is mostly carried out by catalytic hydrogenolysis. [40-41] Considering the experimental safety, the catalytic hydrogen transfer hydrogenolysis is used in this paper, and the hydrogen donor is replaced by hydrogen as ammonium formate, and Pd is used as the catalyst.
Reduction of all carbonyl groups on compound 4 with LAH as a reducing agent gave compound 5 in the yield of 63.33%.
The data from the high-resolution mass spectrometry detection revealed no signal of debenzylated derivative.
Based on the above data, we suspected that the debenzylation of compound 5 could first remove a benzyl group, and then lose another benzyl group to give the debenzylated product 6 (Scheme 2).
