Control Strategies
Control Strategy in Artificial Intelligence
scenario is a technique or strategy, tells us about which rule has to be applied next while searching for the solution of a problem within problem space.
It helps us to decide which rule has to apply next without getting stuck at any point.
Characteristics of Control Strategies
A good Control strategy has two main
characteristics:
Control Strategy should cause Motion
Control strategy should be Systematic
Co ntrol Strategy should cause Motion
Each rule or strategy applied should cause the motion because if there will be no motion than such control strategy will never lead to a solution. Motion states about the change of state and if a state will not change then there be no movement from an initial state and we would never solve the problem.
Co ntrol Strategy should be Systematic
Though the strategy applied should create the
motion but if do not follow some systematic
strategy than we are likely to reach the same state
number of times before reaching the solution
which increases the number of steps. Taking care of only first strategy we may go through particular useless sequences of operators several times. Control Strategy should be systematic implies a need for global motion as well as for local motion.
The development of intelligent network forensic tools to focus on specific type of network traffic analysis is a challenge in terms of future perspective.
This will reduce time delays, less computational resources requirement; minimize attacks, providing reliable and secured evidences, and efficient investigation with minimum efforts

Examine Evidence PartitionsAnalysis of four small partitions ext.docxcravennichole326
Examine Evidence Partitions
Analysis of four small partitions extracted from a suspect's hard drive. Your analysis will assess the nature of each partition—specifically, whether each partition is encrypted, compressed, wiped, or none.
Demonstration and hands-on training are always most effective, so you turn to the former in Step 2. Digital forensic investigators need to understand how to examine evidence partitions. In a case that you are working on currently, the suspect's computer contains four disk partitions. A disk partition is a portion of a whole disk with its own file system. Access the virtual lab to examine evidence partitions in order to determine whether files on each partition are encrypted, defragmented, securely deleted, or none of these. If they have been encrypted, what process was used: NTFS encrypted file systems, BitLocker, PGP, etc.?
After conducting your analysis, you demonstrate how you would document your findings in a formal forensic report. Include descriptions of destruction strategies such as wiping, overwriting, corruption, and degaussing. Make sure these strategies are explained in terms that IT temps, recent hires, and other nonexperts can understand in a consistent way. This will be the first section of your investigative report.
Share this section of the report with a colleague (your instructor) for review and feedback before continuing to the next step, where you will search for hidden data in files. Make sure to incorporate any suggested changes. This will be the first section of the sample investigative report to be included in the job aid submitted in the final step.
Lab Work Instruction:
Examine Evidence Partitions
You are provided four NTFS partitions from a hard drive, each about 100MB in size. One of the partitions has been defragmented, one used file encryption, and one used secure file deletion; no action has been taken on the other. Your task is to determine which action (if any) has been applied to each partition.
You will examine each partition using FTK (Imager is sufficient) and the Windows operating system. Your guidance for determining which actions have been taken on a specific partition are as follows:
Normal (no action):
· files are scattered throughout the partition
· you will see deleted files with content
· you will see data in file slack space
Defragmentation:
· files are stored in contiguous locations
· file slack space is zeroed out
· measurable with native OS tools
Encryption:
· file contents are “jibberish” (very little readable plain text)
· FTK may show a "key" icon
· OS may indicate encryption (e.g., "lock" icon)
Secure Wipe:
· deleted files in unallocated space will not contain any readable content
· there will not be any data in file slack space
To examine each of the partitions, perform the following steps until you are confident about which action was applied to each partition. The partitions for this exercise are raw dumps and are named partition_blue.d.
How to remove files safely from an HDD or SSD in Windows 10Hetman Software
You select a file and press Delete, and it disappears. But what actually happens to the file? Does it vanish or get erased from the disk permanently? If you are an advanced Windows user, you know for sure it’s quite the contrary.
This world have numerous kinds and diversity .This kinds and diversity remain in whole world two two third is aquatic ,fresh water and marine water .This kinds and diversites knowledge and their total knowledge file management is very importance for fisheries science.
This freshwater and marine water has a huge number of vertebrate and invertebrate animals and plants. Thair identify and use is vary importance for fisheries and aquaculture .for that their proper file management is play a useful role in fisheries and aquaculture.
If we went to know the total plant and animals this is not possible to proper file management.
Culturable species and there predator knowledge and file management is vary importance for aquaculture .culturable species habitats and their food habit is very importance for successful aquaculture and also importance in breeding season and behavior and high growth rate fish data .There proper management and for fisheries student study documents is very important. So file management is very importance in fisheries science.
In many ways, directories are treated like files. They can be created, deleted, moved and copied from Nautilus or from a shell prompt, using commands similar to those for files.
Creating Directories
You must have write permissions in a directory in order to create a new sub-directory. Most users have these permissions in their home directory (and its sub-directories) and the /tmp/ directory.
To create a new directory with Nautilus, navigate to the location of your new directory. Right-click in a blank portion of the window and select Create Folder. A new folder icon appears with the highlighted text untitled folder. Type a name for your folder and press [Enter].
To create a new directory using a shell prompt, use the command mkdir. Enter: mkdir <directory-name>, replacing <directory-name> with the intended title of the new directory.
Deleting Directories
To delete a directory from Nautilus, right click on it and choose Move to Trash, or click and drag the icon to the Trash on the Desktop.
To delete an empty directory from a shell prompt, enter the command rmdir. To delete a directory that may not be empty (and consequently everything inside that directory), enter the command rm -rf <directory>. Refer to Section 4.5.5 Delete files with rm for more information regarding the rm command.
Dot Directories
Applications create "dot" directories as well as dot files. Dot files are a single hidden configuration file — a dot directory is a hidden directory of configuration and other files required by the application. The non-configuration files in these directories are generally user-specific, and will be available only to the user who installed them.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

2. Data Hiding
Data hiding involves changing or manipulating a file to
conceal information. Data-hiding techniques include hiding
entire partitions, changing file extensions, setting file
attributes to hidden, bit-shifting, using encryption, and setting
up password protection. Some of these techniques are
discussed in the following sections.
3. Data-hiding Techniques
File manipulation
Filenames and extensions
Hidden property
Disk manipulation
Hidden partitions
Bad clusters
Encryption
Bit shifting
Steganography
5. As we can be seen above, we encountered an error. Now, a typical user
may say this file is corrupt and thus probably delete the file and move on.
While that may be acceptable for the regular user, a forensics analyst
would need to dig a little deeper.
To dig a little deeper, our shovel will be HxD Hexeditor. A point to note is
that every file type has a header which can be used as a signature to
identify the type of file. Similarly some file types have known trailers,
which marks as the ending of the file. Considering this information, we can
use the Internet to our advantage to learn about file extensions. To
determine our actual file type we will rely on the work already done by
https://www.garykessler.net/library/file_sigs.html.
Let’s open our file in Hx.
Filenames and extensions (continued)
7. If we compare the first 6 bytes “7B 5C 72 74 66 31” to one of the known
entries on garykessler.net, we can see that this file should have an
extension of .rtf. In addition, if we look at the trailer we see that within the
last 10 bytes, we have a 4 byte sequence “5C 70 61 72” that matches part
of the .rtf extension. Let’s focus on the header and change the file to .rtf
instead of .jpg.
The file extension can be changed by either renaming the file in “Windows
Explorer” or by “ren securitynik.jpg securitynik.rtf” in the command
prompt.
Filenames and extensions (continued)
8. Hiding Partitions
Delete references to a partition using a disk editor such as Norton
DiskEdit, this editor will delete any reference to it manually.
Re-create links for accessing it.
Use disk-partitioning utilities
GDisk
Partition Magic
System Commander
or Linux Grand Unified Bootloader (GRUB), which provides a startup
menu where you can select an OS. The system then ignores other
bootable partitions.
Account for all disk space when analyzing a disk
9. For example, in the following code, Disk Manager recognizes the extended
partition (labeled EXT DOS) as being 5381.1 MB (listed as Mbytes). The
LOG DOS labels for partitions E through F indicate that they’re logical
partitions that make up the extended partition. However, if you add the
sizes of drives E and F, the result is only 5271.3 MB, which is your first
clue to examine the disk more closely. The remaining 109.8 MB could be a
previously deleted partition or a hidden partition. For this example, the
following code shows the letter “H” to indicate a hidden partition.
Hiding Partitions (continued)
10. Hiding Partitions (continued)
In fig 1.1 you can see a hidden partition in Disk Manager, which
shows it as an unknown partition. In addition, the drive letters in the
visible partitions are nonconsecutive (drive I is skipped), which can be
another clue that a hidden partition exists. Most skilled users would
make sure this anomaly doesn’t occur, however.
Figure 1.1 Viewing a hidden partition in Disk Manager
11. Hiding Partitions (continued)
In ProDiscover, a hidden partition appears as the highest available drive letter set in the
BIOS. Figure 1.2 shows four partitions, similar to Figure 1,1, except the hidden
partition shows as the drive letter Z. To carve (or salvage) data from the recovered
partition gap, you can use other computer forensics tools, such as FTK or WinHex.

12. Marking Bad Clusters
Common with FAT systems.
Place sensitive information on free space.
Use a disk editor to mark space as a bad cluster
To mark a good cluster as bad using Norton Disk
Edit
Type B in the FAT entry corresponding to that
cluster
13. Bit-shifting
Old technique
Shift bit patterns to alter byte values of data
Make files look like binary executable code
Tool
Hex Workshop
Bit-shifting changes data from readable code to data that looks like binary
executable code. Hex Workshop includes a feature for shifting bits and altering
byte patterns of entire files or specified data. To shift bits in a text file, follow
these steps
14. Bit-shifting (continued)
1. Start Notepad, and in a text document, type TEST FILE. Test file is to see how
shifting bits will alter the data in a file.
2. Save the file as test file.txt in your work folder, and exit Notepad.
3. Start Hex Workshop. Click File, Open from the menu. Navigate to your work
folder, and then double-click test file.txt. Figure 3 shows the file open in Hex
Workshop
figure 3 test file.txt open in Hex Workshop
15. 4. To set up Hex Workshop for the bit-shifting exercise, click Tools >> operations
from the menu.
5. In the Customize dialog box, click the Data Operations check box, and then click
OK.
6. Click the Shift Left button (<< icon) on the Data Operations toolbar. The Shift
Left Operation dialog box opens (see Figure 4), where you specify how you want to
treat the data, the ordering scheme to use for bytes, and whether you shift bits for
selected text or the entire file.
Figure 4 The Shift Left Operation dialog box
Bit-shifting (continued)
16. 7. Click OK to accept the default settings and shift the bits in test file.txt to the left.
8. Save the file as Bit_shift_left.txt in your work folder. Figure 5 shows the file in
Hex Workshop, with the @ symbols indicating shifted bits.
Figure 5 Viewing the shifted bits
Bit-shifting (continued)
17. 9. To return the file to its original configuration, shift the bits back to the
right by clicking the Shift Right button (>> icon) on the Data Operations
toolbar. Click OK to accept the default settings in the Shift Right
Operation dialog box. The file is displayed in its original format.
10. Save the file as Bit_shift_right.txt in your work folder, and leave Hex
Workshop open for the next activity
Bit-shifting (continued)
18. Using Steganography to Hide Data
Greek for “hidden writing”
Steganography tools were created to protect copy righted material
By inserting digital watermarks into a file.
EXAMPLE: to notify users that an image is copyrighted. The digital
watermarks used for steganography aren’t usually visible, however,
when you view the file in its usual application and might even be
difficult to find with a disk editor. A non steganographic graphics file is
the same size as an identical steganographic graphics file, and they
look the same when you examine them in a graphics viewing utility,
such as IrfanView. However, if you run an MD5 or SHA-1 hash
comparison on both files, you’ll find that the hash values aren’t equal.
19. EXAMPLE:
To hide data, people can use steganography tools, many of which are
freeware or shareware, to insert information into a variety of files. If you
encrypt a plaintext file with PGP and insert the encrypted text into a
steganography file, for example, cracking the encrypted message is
extremely difficult. However, most steganography tools can insert only
small amounts of data into a file and usually require a password to restrict
access to the inserted data.
Suspect can hide information on image or text document files.
Very hard to spot without prior knowledge.
