1. Fence wire
Defect: The fence wire has been tangled and twisted in a way that small animals may enter the premises and anybody can get hurt.
Cause: The process was not followed properly to create proper fencing or while fencing, proper tools were not used to complete the entire job.
Prevention: The procedure should be followed thoroughly using proper material and tools and proper inspections should be done at the end of the job.
2. Cracked sidewalk
Cause: The process was not followed properly to create proper fencing or while fencing, proper tools were not used to complete the entire job.
Prevention: The procedure should be followed thoroughly using proper material and tools and proper inspections should be done at the end of the job.
2. Cracked sidewalk
Defect: The bricks used in the sidewalk have been broken and placed in an irregular manner.
Cause: The bricks were either placed when they already had cracks in them, which would mean the work was done with damaged material. Another possibility is that the cracks occurred after the bricks were installed and hence, the excessive use of heavy material caused the cracks in the sidewalk. One other reason through which these cracks could occur is if the land below the bricks is porous which results in voids.
Prevention: The materials used should be thoroughly inspected before installation, even the base surface should be inspected as well if it is fit to be used or not. If not, proper procedure should be followed to make it usable. There should be restrictions to certain heavy usage which can cause this sort of damage.
3. Misaligned structure
Cause: The bricks were either placed when they already had cracks in them, which would mean the work was done with damaged material. Another possibility is that the cracks occurred after the bricks were installed and hence, the excessive use of heavy material caused the cracks in the sidewalk.

If not, proper procedure should be followed to make it usable. There should be restrictions to certain heavy usage which can cause this sort of damage.
3. Misaligned structure
Defect: The hoarding structure on the top of the garage is misaligned
Cause: The support structure created was not strong enough to hold the holding properly or the holding was installed originally in an irregular manner.
Prevention: Stronger materials should have been used to support the holding. Metal planks could have been used in place of wooden planks. A cautious approach should be followed while installing the holding.
4. Misaligned wooden planks
Cause: The support structure created was not strong enough to hold the holding properly or the holding was installed originally in an irregular manner.
Prevention: Stronger materials should have been used to support the holding. Metal planks could have been used in place of wooden planks. A cautious approach should be followed while installing the holding.
4. Misaligned wooden planks
Defect: The wooden planks on the sidewalk installed are irregular and have gap between them.
Cause: While installing the planks they did not consider the level and regularity of planks. Planks seem to have been weared out which means that these planks were not being maintained to prevent erosion.
Prevention: If proper planning had been done while installing the planks and if the planks had been cut as required, this error could have been avoided.
5. Broken chair
Defect: The hold joints used to join the back support and the chair has been broken causing the back support to detach from the chair.
Cause: The hold joints used in the chair must have been would be of poor quality which in due course of time broke and caused the chair to break. Or there could have been an issue in assembling the chair.
Prevention: The hold fasts used in the chair should have been of better quality to hold the load. Also proper mechanism should be followed to cross check if the joints are tight enough to make sure that the chair doesn't fall apart.

6. Cracked ceiling
Defect: The Armstrong used in the ceiling has developed a crack and has lost its finishing from the sides.
Cause: The Armstrong used in the ceiling must be of poor quality which in due course of time started to degrade and hence, the cracks and deformities started to appear in the Armstrong.
Prevention: The materials used should be proper quality standards and should be passed through inspection of quality control so that the use of substandard quality substances can be avoided.
7. Corroded and irregular cut-outs
Cause: The Armstrong used in the ceiling must be of poor quality which in due course of time started to degrade and hence, the cracks and deformities started to appear in the Armstrong.
Prevention: The materials used should be proper quality standards and should be passed through inspection of quality control so that the use of substandard quality substances can be avoided.
7. Corroded and irregular cut-outs
Defects: By comparing the holes in two similar tables, we can say that the cut made in one table is perfect and there is an error in the hole of the other table. Also, hole in one of the table has been corroded.
Cause: There is a human error while cutting hole in the table, either a person with insufficient skill tried and cut the hole or the tool used to cut the hole had issues in it. Also, corrosion must have occurred as a result of not covering the inside of the hole with an anti-rust spray or paint.
Prevention: A person with proper skill set should do this sort of a job with all the efficient tools required. These metallic tables should be regularly sprayed with anti-rust sprays to increase its life.The best alternative is to automate this process as it is impossible for humans to achieve 100% geometry in cutting out such stuff.
8. Door hinges
Cause: There is a human error while cutting hole in the table, either a person with insufficient skill tried and cut the hole or the tool used to cut the hole had issues in it. Also, corrosion must have occurred as a result of not covering the inside of the hole with an anti-rust spray or paint.

8. Door hinges
Defect: The hinge in the cupboard has fallen apart and hence caused the door to be tilted and fall on one hinge
Cause: The screws used to fix the hinge would not have been affixed properly in the cupboard or the hinge would be of lower grade of quality which caused the fracture of the hinge.
Prevention: The screws used to affix the hinge should be fixed using fasteners which would help them hold a better grip and would run for a longer time. In case the hinge is of poor quality then the hinge should have been passed through quality control check after its production and a certain inspection of the products can avoid usage of the substandard quality substance.
9. Melted spoon

How effective power management increases the lifetime of portable medical devices
I think this is a very interesting topic. It is very rightly said that the medical device teams often focus on core technology rather than support systems. These people don’t really emphasize on the power design which leads to basic mistakes that impact the performance, lifetime, efficiency and cost of the final product. In my opinion, the core unit of any portable medical device is its power source i.e. battery. Another important aspect is to design circuit boards that consume less energy. So considering these two aspects in designing portable devices would prove to be cost and power effective.
However, one of the participants on Moodle suggests that there are many other factors which should be taken into consideration such as the price of the product, reliability, compact design, lifetime, and high-performance, the comparative analysis experiments to determine what should be the best combination to design a good portable medical device that meets the best quality requirements.

Computers Conquer Texas Hold'em Poker for First Time
The idea of solving a game of poker seems to be very interesting to me. I agree with Davide that the approach used by Burch is certainly quality oriented. Though the article focusses on a game here, the major benefit I see here is that these algorithms may be used in the real world. For instance, the algorithm could help develop strategies for security officials to deploy certain resources—maybe a bomb-sniffing dog or Coast Guard patrol boat—to certain areas at different times of the day without getting predictable. . The fact that the memory requirements have been reduced from the past is an indicator that with further research and development, memory requirements can be compressed further. Other participants on Moodle believe that is a great example of Lean Jidoka as these guys were able to minimize the amount of space required for this algorithm by making it more efficient. Also the algorithm is designed to learn from its own mistakes.
This example is certainly a good illustration of total quality management.

Use of Thin-Film Thermoelectrics in PCR Thermal Cycling
The article talks about using thin-film thermoelectrics in PCR Thermal Cycling. I agree with Gilles as it would help researchers to quickly date the DNA in the field instead of spending years in the traditional laboratories. Thin-films enable a new generation of compact thermal cyclers that feature significantly shorter throughput times, smaller sample sizes, and reduced footprint for real-time testing in healthcare, forensics, and food safety. It will not just reduce the analysis time, but also increases the portability. I think it will give LAIRD a competitive advantage in the market and will prove to be really helpful and useful.
