How to Fix Lower Back Pain

Those days when our ancestors were the young stars, back pain was only for the old. But recently, everybody suffers from back pain even a child that has been born is prone to back pain. What causes back pain? When your posture is not upright you are likely to experience back pain, when one of the muscles at your back is injured you are likely to experience back pain, when you hit the gym and weightlift in a wrong way, when you do not do adequate exercise and many more others.

Lower back pain occasionally tends to be so sharp that the infected person can’t make any motion or afford an upright
posture. This mostly results from major injuries caused by poor weight lifting or during a sporting activity. At a times the pain may be referred to as chronic. What does this mean? A pain that goes for a duration of three months or more. Such kind of long-lasting pain should never be taken lightly but the infected should make efforts of visiting a specialist at any hospital for a thorough medical screening and checkup.

How can you fix your lower back pain without seeking medical attention? There are some stretching techniques you can
apply to fix it, or even anti-inflammatory aids likeĀ

Restful Pose;

This is a common type of pose in Yoga that helps in the general body relaxation. How is it done? On the floor, ensure that your knees are widely placed as compared to your hip, stretch your hands in front forward away from your body. Push your hipbone behind to meet your heel. Relax on this posture for at least 20 seconds. Come up again and repeat the procedure at least three times.

Cobra stretch;

Have you ever seen a cobra when ready to attack? The way it raises its head for proper vision? In yoga, we have the cobra stretch. How is this stretch done? First, lay flat on the floor, position your hands at the kidney area with an open palm, and then gently push your upper body up letting your arms support your weight until you reach that position you feel very comfortable at then relax there for 8-1 0 seconds.

Move back to your initial posture and repeat the procedure three times. This exercise is vital in stretching the lower back and the muscles located around the abdomen.

Knee to chest;

How is this done? First of all, lie on your back or facing the sky, with your toes facing upwards. Gently bend your left knee and bring it towards your chest. Use both hands to hold your things then try making your knees reach your chest. At a comfortable position, hold on it for 15-20 seconds and then gently allow the knee back to its normal position. Repeat this procedure three times for each knee.

This kind of stretch is important in stretching the lower back, and the pelvis alignment.

The above three stretching exercises are not meant for medical purposes but they are locally proven ways of relieving the lower back pain. Thus it is important to keep them in practice at home or at the gym.

Field Programable Gate Array and some of its uses

A FPGA or Field Programable Gate Array is a programable piece of electronic circuitry. Traditionally they have been used in high performance computing, Radars, Ultrasound, Optical networks and wireless communications. Typically, they are divided into cells (ALM, LE), which are arrays od logic blocks and IIO interface pads and routing channels. They are programmed
with algorithms of logic using look up tables (LOT) to perform a specific task, like timing (clock signally) or route information. They can be used many times in complex systems, as well as in conjunction with SDRAM (extended memory) and EEPROM (programable chips).

They are available in two types systolic array or crossbar switch with requires further rooting (which is higher in cost). Efficiency with capacity is important for cost because used tracks further add cost to the best price on fpga, usually Rent’s rule is used for design purposes.

They are typically used in 30 architecture (3 levels of data), where FPGA are die stacked side by side for complex logic gate systems programming. Modern FPGA usually has further abilities directly built into the silicon, known as hard blocks. These dedicated hardware systems improve performance are faster at logic calculates and general functionality.

FPGA synchronous circuitry requires a clock signal to function, whilst complex systems have multiple clocks with more than one frequency via clock domains. Devices use a serial interface to communicate with the FPGA and a calculated result will be returned to enable the device to function correctly (setting, features, timing etc), so settings on an ultrasound or distance to object on radar and its format for example.

In this way the FPGA become part of the system hardware integration of the design and first prepared and designed via schematics or circuit diagrams. The FPGA is designed in stages using a language called FPGA;

  • Synthetic engine (mapped)
  • Netlist (place and route)
  • Gate level description (HDL)

Whilst the software processes are done in VHDL (electronic design
automation), the hardware for the logic gate design is written in HDL or
Hardware Design Language. HDL works with large structures and it defined
numerically for simplicity, although schematic entry is possible.

From synthetic engine to netlist the process needs to be error check and function confirmed at each above stage. With the last two stages repeatedly communicating with each other to confirm accurate error free design and

Finally, the design is programmed (netlist) to the FPGA, propagation delays are added to fine tune timing execution, with a simulation ran and back annotated onto the Netlist.

More recently OpenCL has been used to program FPGAs because of improved performance and power efficiently, this involves OpenCL Kernels and constructs (programming architecture).

Major manufacturers are Xilinx and Altera, usually provided with OS software to complete the design and program stages, as per above. Netlist is fit the FPGA architecture using a process called place and route. Used software provided with from manufacturer. This complex process all combine, to allow many electrical devices to be design and their logical processes design defined, first in software they written to dedicated hardware, where they are packaged into a final product for market.

Intel has recently acquired Altera (2015), for $16.7 billion, demonstrating how fundamental hardware technology is through all our working and personal lives. Intelligent design, through sensible engineering.
